The coupling characteristics and mechanism of farmland and rural housing land transition in China

Land use transition refers to the changes in land use morphology （both dominant morphology and recessive morphology） of a certain region over a certain period of time driven by socio-economic change and innovation, and it usually corresponds to the transition of socio-economic development phase. In China, farmland and rural housing land are the two major sources of land use transition. This paper analyzes the spatio-temporal coupling characteristics of farmland and rural housing land transition in China, using high-resolution Landsat TM （Thematic Mapper） data in 2000 and 2008, and the data from the Ministry of Land and Resources of China. The outcomes indicated that： （1） during 2000-2008, the correlation coefficient of farmland vs. rural housing land change is -0.921, and it shows that the change pattern of farmland and rural housing land is uncoordinated; （2） the result of Spearman rank correlation analysis shows that rural housing land change has played a major role in the mutual transformation of farmland and rural housing land; and （3） it shows a high-degree spatial coupling between farmland and rural housing land change in southeast China during 2000-2008. In general, farmland and rural housing land transition in China is driven by socio-economic, bio-physical and managerial three-dimensional driving factors through the interactions among rural population, farmland and rural housing land. However, the spatio-temporal coupling phenomenon and mechanism of farmland and rural housing land transition in China are largely due to the ＂dual-track＂ structure of rural-urban development.

Productive functional evolution of rural settlements:analysis of livelihood strategy and land use transition in eastern China

In China, rural settlements are usually multifunctional complex of natural societies and they also play important productive function. This study explored the spatiotemporal evolution of the productive function of three rural settlements, i.e.,Hetaoyuan, Dawengshan, and Gaoqiao, in the Yimeng Mountain in Shandong province of eastern China.Residents lived in this three types of rural settlements were all involved in agricultural production(i.e., grain threshing, drying and storage), which had remained dominant in Hetaoyuan. Dawengshan became an industrial-oriented settlement, while Gaoqiao became a commercial-oriented settlement. This evolution was reflected in the livelihood strategy changes of rural households and the transition of rural settlements changes. The choice of livelihood strategy was affected by the livelihood assets and policies, which resulted in the spatiotemporal evolution of the productive function of rural settlements. This study can provide references for the implementation and adjustment of rural residential land consolidation policies and the improvement of production and the quality of rural life in future.

Analysis on the Transition of Resource-based Rural Land Use in the Context of Rural Revitalization:A Case Study of Taolingou Village,Yangquan City,Shanxi Province

The key to the transformation of resource-based rural economy lies in the land use transition,which has important theoretical and practical significance for the reconstruction of rural values and the promotion of rural revitalization.Taking Taolingou Village in Yangquan City,Shanxi Province as an example,on the basis of expounding the concept and connotation of land use transition,this paper analyzes the evolution trend of resource-based rural land use transition,explores the driving force of resource-based rural land use transition and clearly puts forward the measures to strengthen the transformation of resource-based rural land use in the context of rural revitalization.The analysis shows that the land use of Taolingou Village is transforming towards the trend of sustainability,putting people first and multi-function,which is consistent with the strategic goal of rural revitalization.The driving force of land use transition in Taolingou Village includes four aspects,namely,industrial structure,economic factors,development policy and contradiction between human and land.Adjusting and optimizing the industrial structure,protecting the ecological environment,perfecting relevant policies and regulations,and controlling the overall population are the effective measures for Taolingou Village to realize the land use transition.This case study is expected to provide a useful reference for the land use transition in other resource-based rural areas.

Land consolidation： An indispensable way of spatial restructuring in rural China

The implementation of new type industrialization and urbanization and agricultural modernization strategies lacks of a major hand grip and spatial supporting platform, due to long-term existed ＂dual-track＂ structure of rural-urban development in China as well as un- stable rural development institution and mechanism. It is necessary to restructure rural pro- duction, living and ecological space by carrying out land consolidation, so as to establish a new platform for building new countryside and realizing urban-rural integration development in China. This paper develops the concept and connotation of rural spatial restructuring. Basing on the effects analysis of industrialization and urbanization on rural production, living and ecological space, the mechanism of pushing forward rural spatial restructuring by carry- ing out land consolidation is probed. A conceptualization of the models of rural production, living and ecological spatial restructuring is analyzed combining with agricultural land con- solidation, hollowed villages consolidation and industrial and mining land consolidation. Fi- nally, the author argues that a ＂bottom-up＂ restructuring strategy accompanied by a few ＂top-down＂ elements is helpful for smoothly pushing forward rural spatial restructuring in China. In addition, the optimization and restructuring of rural production, living and ecological space will rely on the innovations of regional engineering technology, policy and mechanism, and mode of rural land consolidation, and more attentions should be paid to rural space, the foundation base and platform for realizing urban-rural integration development.

Contributions of Social-ecological Drivers to Land Use Transitions in Protected Areas on the Tibetan Plateau:Shifting from Strong Intervention to a New Balance

The establishment and management of protected areas(PAs)often involve modifying traditional land use rights and changing the production and living activities of locals,which can lead to changes in the factors that drive land use transitions.Our understanding of the spatiotemporal patterns of land use transition and the contributions of social-ecological drivers remains incomplete.In this study,we focused on the Yarlung Zangbu Grand Canyon National Park and examined how social-ecological factors influence land use transitions by developing a theoretical model of land use transitions within PAs.Our findings revealed that cropland,shrubland,grassland,and wetland experienced net losses in area,while forestland,water,ice/snow,barren land,and impervious land exhibited fluctuating growth patterns from 1985 to 2020.The net decrease in grassland was 157425.60 ha,while the net increase in forest was 140709.20 ha.The quality of land habitat increased from 0.5158 to 0.6656.Land use dominant and recessive transitions displayed varying spatial characteristics and scales across different time periods.In particular,the degree of influence of policy factors on land use dominant transition declined from 0.0800 in 1985-1990 to -0.0432 in 2010-2020,while its influence on land use recessive transition declined from 0.00058 in 1985-1990 to 0 in 2010-2020.The results show that social-ecological factors intricately influenced different types of land use transitions,leading to a shift from a balanced state to a new equilibrium.These results enhance our understanding of the spatiotemporal patterns and complex dynamics of land use transitions within PAs,providing insights and practical implications for effective land management in PAs by considering the land-human relationships.

劳动力变动背景下耕地利用隐性形态影响因素分析——基于农户生产投入意愿与行为视角

Land use transition occurs through changes in land use morphologies.The decision-making and land use behavior of farmers is the main factor that causes changes in the land use system and subsequent transitions of land use.This study focused on the recessive morphologies of farmland based on the investment in agricultural production inputs by farmers,and established an analytical framework based on induced technological innovation theory and farmers’ behavior theory,which followed the pathway of “objective-willingnessbehavior.” Using survey data for farming households in two counties(Shouguang and Yiyuan) in Shandong province,the main factors influencing farmers’ willingness to invest in agricultural production and their differences under the background of labor force changes were comprehensively analyzed with a binary logistic model and ordinary least squares(OLS) regression model.The aim was to provide decision-making guidance for promoting farmland use transition.There were three key results.(1) The scale management objectives of a farmer were limited,with 75% of farmers intending to maintain the current farmland management scale,and planning to retire at an advanced age,although there were regional differences in these phenomena.(2) Farmers’ willingness to invest in agricultural production inputs was closely related to agricultural production objectives,farmland use,and agricultural production,whereas the labor structure had no significant effect.Farmers’ behavior toward investment in agricultural production inputs was negatively related to their expected retirement age.Changes in the household labor structure were an important factor boosting farmers’ investment in agricultural production inputs.(3) It is essential to better understand the cognitive level and structure of farmers,and the characteristics of the labor structure and type of agricultural development could be combined to improve the farmers’ cognitive level and willingness to adopt scale management objectives and generate behavioral responses.Using the dual scale of “land + service” would overcome the structural obstacles faced by farmers,and effectively play the role of providing both policy incentives and regulation.

土地利用转型与乡村空间治理——机制、框架与展望

The pattern for utilization of rural space is closely related to rural transformationdevelopment (RTD). The problem of rural space utilization is an important manifestation of theuncoordinated relationship between land use patterns and rural development status during atransformation period. Considering the rural space utilization issue, this article seeks to analyzethe interaction mechanisms between land use transition (LUT) and rural spatial governanceand then build a rural spatial governance analysis framework based on LUT. Also, thepaper explores the internal relationship between rural spatial governance and rural vitalizationand discusses the research prospective of the interaction. The study found that: (1) Ruralspace utilization has systemic problems such as limited development space, ill-defined ownershipand poor organization, which have become important obstacles for rural development.(2) The uncoordinated relationship between LUT and RTD is an important reason for the dilemmasurrounding rural space utilization. (3) The LUT provides a basis for determining thetiming of rural spatial governance, specifying spatial governance objectives, and clarifyingrural spatial governance methods. (4) The construction of a comprehensive analysis frameworkof “matter-ownership-organization” of rural space based on the LUT has created conditionsfor the orderly promotion of rural spatial governance. (5) Rural spatial governance whichfacilitates the integration of urban-rural development is an important foundation for rural vitalization.(6) Interaction analysis of LUT, RTD and rural spatial governance is conducive tofacilitating research on the operational mechanism of rural regional systems and to expandingthe research field of rural geography.

Using counties as the basic analysis unit, this study established an evaluation index system for farmland function （FF） from economic, social, and ecological perspectives. The method combining entropy weighting and multiple correlation coefficient weighting was adopted to determine the weights, and the FF indices were calculated for each county. Sub- sequently, the spatio-temporal characteristics of farmland function evolution （FFE） were an- alyzed and the coupled relationships between the sub-functions were explored based on a coupling coordination model. At the same time, the dynamic mechanism of FFE was quanti- tatively analyzed using a spatial econometric regression analysis method. The following ma- jor conclusions were drawn： （1） The farmland economic function generally exhibited a de- clining trend during 1990-2010, and it is essential to point out that it was stronger in under- developed and agriculture-dominated counties, while it continuously weakened in developed areas. Farmland social function decreased in 60.29% of the counties, whereas some counties which were mostly located in north of Zhengzhou and west of Dezhou and Cangzhou, Yantai, and Weihai, clearly increased. A dramatic decline in farmland ecological function occurred around Beijing, Tianjin, and Jinan. Areas located in the northern part of Henan Province and the central part of Shandong Province saw an increase in ecological function. （2） There was a significant spatial difference in the coupling degree and coordination degree of the sub-functions, and the decoupling phenomenon highlighted this. The changes in social func- tion and ecological function lagged behind economic function in developed areas, but these were highly coupled in some underdeveloped areas. （3） FFE in the Huang-Huai-Hai Plain （HHHP） is resulted from the comprehensive effects of regional basic conditions and external driving factors. Furthermore, the transitions of population and industry under urbanization and industrialization played a decisive role in the evolution intensity and direction of farmland sub-systems, including the economy, society, and the ecology. According to the results men- tioned above, promoting the transformation from traditional agriculture to modern agricultureshould be regarded as an important engine driving sustainable development in the HHHP. Taking different regional characteristics of FFE into account, differentiated and diversified farmland use and management plans should be implemented from more developed urban areas to underdeveloped traditional agricultural areas.

黄淮海平原农区土地利用转型及其动力机制（英文）

Land use transition refers to changes in land use morphology, including dominant morphology and recessive morphology, of a particular region over a period of time driven by various factors. Recently, issues related to land use transition in China have attracted interest among a wide variety of researchers as well as government officials. This paper examines the patterns of land use transition and their dynamic mechanism in the Huang-Huai-Hai Plain during 2000-2010. First, the spatio-temporal patterns of land use transition, their character- istics and the laws governing them were analyzed. Second, based on the established con- ceptual framework for analyzing the dynamic mechanism of land use transition, a spatial econometric regression analysis method was used to analyze the dynamic mechanism of the five types of major land use transition in the Huang-Huai-Hai Plain at the county level. Land use pattern changes in the study area were characterized by an increase in construction land, water body and forested land, along with a decrease in farmland, unused land and grassland. The changes during 2000-2005 were much more significant than those during 2005-2010. In terms of factors affecting land use transitions, natural factors form the basis, and they have long-term effects. Socio-economic factors such as population and GDP, however, tend to determine the direction, structure, size and layout of land use transition over shorter time periods. Land law and policy factors play a mandatory guiding and restraining role in land use transitions, so as to improve the overall efficiency of land use. Land engineering is also an important tool to control land use transitions. In general, the five types of major land use transition were the result of the combined action of various physical, social and economic factors, of which traffic condition and location condition had the most significant effects, i.e. they were the common factors in all land use transitions. Understanding the spatio-temporal process of land use transitions and their dynamic mechanisms is an important foundation for utilizing land resources, protecting regional ecological environment and promoting sustain- able regional socio-economic development.
