Family Farm Development in Southern Jiangsu and Countermeasures with a Case Study

The research reviewed the concept of family farm and analyzed family farm types including unified, facility rental-oriented, employment-oriented, circular and grain＆oil based family farms, as well as corresponding demands in technology and policies. Based on the analysis, the research proposed countermeasures and suggestions. It is necessary to define the range and scale on family farm before giving policy supports. It is important to establish access system of industry and commerce capital to rural areas to guarantee the operators in need be benefited from national preferential policies. Meanwhile, new system on land transfer should be established to guarantee security system for family farm, improve socialized service system and promote government-built production facilities operated by farmers.

Scale-free Structure of Town Road Network in Southern Jiangsu Province of China

From the viewpoint of Graph Theory this paper builds a town road network graph of regional scale, and proposes numerical vertex degree （Di）, rank vertex degree （Dr） and population size vertex degree （Dp） on the base of vertex degree （D）. Then the indicators of Di, Dr, Op and mathematical statistics methods are applied to investigating scale-free structure of town road networks in the southern Jiangsu Province. The results show that the distribution of Oi does not exhibit scale-free properties, but Dr and Dp do. Additionally the correlation coefficient between Dp and Di is only 0.569, but the spatial correlation between Dp and Dr is very evident on the base of correlation analysis and spatial analysis of GIS. The mutual mechanism between Dp and Dr spatially represents a ＂Core-Belt＂ model of town development of regional scale. The town development model is open and clustered, and beneficial to both economic development and ecological protection. And then we suggest that Suzhou City, Wuxi City, Changzhou City and Wujin City control towns＇ high-density pattern by conducting centralization and consolidation policies, and properly controlling and planning higher rank roads; whereas Nanjing City, Zhenjiang City, Jintan City and Liyang City must strengthen the development of towns along higher rank roads.

Among them, 8 were caused by deuteromycotina and 2 were caused by subphylum basidiomycetes. It was pointed out that the disease regularity was directly related to the pathogenic bacteria, temperature and humidity, microclimate and hedgerow growth. For the first time, the ecological control method of hedgerow disease which focused on ecological health maintenance was put forward.

The evolutionary trajectory of the rural settlements in Southern Jiangsu in the past 20 years:From the perspective of urbanization and land use

For a long time,due to lack of accurate data covering large areas,it is difficult to capture the continuous spatial evolutionary trajectory of rural settlements shaped by rapid urbanization and rural land use policies.To fill this gap,based on theoretical analysis this paper systemically detected the changing characteristics of scale,spatial morphology,distribution,and land use pattern of rural settlements in Southern Jiangsu in the past 20 years depending on the data of land resource survey in 2009 and 2019.The study suggests that the total area and per capita size of rural settlements declined by 30%and 2%respectively as a result of rural land consolidation and the influx of enormous immigrants from underdeveloped regions.The spatial density and average shape index dropped by 14%and 44%respectively in the recent decade,indicating an evident trend of decentralization in spatial distribution,and regularization in the spatial morphology.Furthermore,residential land within rural settlements decreased by 33%over the past decade while the land for industry and commercial service steadily increased,demonstrating that the function for manufacturing and diversified services had been strengthened.Considering the emerging issue of the aging population and new business opportunities in rural Southern Jiangsu,rural settlements regeneration might be the focus offutureresearch.

Reform of Rural Planning in Southern Jiangsu in the Context of the New Normal: A Case Study of Suzhou

As China's economic development enters the new normal stage, the rural development mode and trend will assume new features. Rural planning must be reformed to adapt to the new rural development law accordingly. Focusing on Southern Jiangsu where rural study and planning began earlier than other areas, this paper takes Suzhou as an example and analyzes the features of rural planning in Southern Jiangsu through stage division, based on the internal logic of new normal development. It points out that rural planning of Southern Jiangsu has experienced a "normal to abnormal" development transition. After summarizing existing problems in the planning process, as well as new demands brought to planning by rural development under the new normal stage, this paper also puts forward the reform directions and thoughts of rural planning in Southern Jiangsu from the perspectives of planning value idea, planning drafting system, and planning management mechanism.

In addition, their generation mechanisms arealso discussed from the cataclastic rheology, the dynamic differentiation and the simpleshearing, specially, from the Ode strength theory. Finally, a generative relationship betweenthe ductile deformation domain of the brittle fault system, in the regional layer--slip andthe formation of the stratabound ore deposit is shown as well.

The Path of Rural Revitalization in Rapidly Urbanizing Areas: Taking Southern Jiangsu as an Example

Issues relating to agriculture, countryside, and farmers(called "sannong" in Chinese) are fundamental to China as they directly influence the stability of the country and the well-being of Chinese people. The 19 th CPC National Congress proposed a strategy of rural revitalization, giving priority to the development of "sannong" to promote the modernization of agriculture and the countryside. Since China's reform and opening up, Southern Jiangsu has experienced rapid urbanization and industrialization along with the development of township and village industries, making its urbanization rate reaching 75.9%. While significant achievements have been made in urban and rural development, there are still many challenges in rural revitalization. Based on analysis on the characteristics and problems of rural development in Southern Jiangsu, this paper, aiming at rural revitalization, puts forward methods and paths of rural revitalization, such as value cognition, layout optimization, industrial revitalization, ecological livability, and rural governance, which are of practical significance to promote the integrated urban-rural development and the healthy rural development in the region and to provide a reference of rural development for other areas of the country.

对鹤见和子“内发型发展论”的再反思——基于《农村振兴和小城镇问题》

在国际农村发展领域,对乡村内生动力的关注由来已久。20世纪七八十年代,日本学界兴起对“如何激发乡村内生发展动力”问题的讨论,并适时提出“内发型发展”的理论主张,引起了世界范围内对农村发展问题的探讨,同时促进了发展理论的转型。为追本溯源,进一步揭示“内发型发展论”的本质特征,本文回顾了鹤见和子对费孝通、柳田国男两位学者的研究,对比中国“苏南”与日本“大分”两地在探索“内发型发展”的实践过程中各自形成的独特模式,以深入探究“内发型发展”的理论价值与实践意义,这对当下乡村振兴具有重要的参考作用。

乡村地域工业用地空间重构研究——以苏南地区为例

国土空间重构能够有效提升自然资源节约集约利用水平,推动经济社会高质量发展。文章在分析苏南地区乡村工业用地的演变特征和乡村工业用地空间重构的必要性与紧迫性基础上,明晰苏南乡村工业用地空间重构存在的困境,理顺其空间重构基本框架与产权融合机制,诠释了产权融合视阈下乡村工业用地空间重构的实施路径。总体看,苏南地区乡村工业发展已进入转型优化期,但产业规模小而散、土地权属杂而混乱、土地产出低而有限。政府投入收益倒挂、土地权属协调困难和破碎土地整合路径不畅等问题仍然存在,严重阻碍了乡村存量工业用地空间重构与价值提升。未来应当引入产权融合治理机制,理顺不同产权结构和主体之间利益博弈,通过归宗整合、用地置换和连片自改等路径实现空间重构,以提升乡村工业空间价值。

农村基层法治文化建设实践考察与路径优化——以苏南农村为对象的分析

弘扬宪法精神,推进全面依法治国,建设社会主义法治文化是基础性工程。深化农村基层法治文化建设不仅是提升公民法治素养的必由之路,更是基层治理现代化的题中之义。法治文化建设在苏南农村基层有着参与主体、外部保障、建设形式上的独到之处,但其整体仍处于法律知识普及不够深入、法治思维有待形成、法治信仰亟待建立的状态。农村基层的法治文化建设需要实现与传统文化融合、与党规同频共振、增强主体互动、提高外部保障等目标,从而为全面提升基层社会治理能力、推动实施乡村振兴战略提供牢固的法治保障。

共生理论视角下市域产教联合体实践的问题审视和建构路径——以苏南地区为例
