Design of Practice Teaching for Science of Land Management

The Science of Land Management is a course integrating theory and practice closely.In order to improve the teaching effect of the course and practice the course,this paper discussed practice work related to main contents of the Science of Land Management.On the basis of taking overall consideration of the status and functions of this course in the entire teaching system,this paper designed three practice teaching parts closely connected with the core contents.This is of realistic significance for improving the teaching quality of the Science of Land Management.

Journal of Arid Land selected for coverage in Cambridge Science Abstracts and Centre for Agriculture and Bioscience Abstracts

In November 2011, Journal of Arid Land （JAL） was accepted for indexing in Cambridge Science Abstracts （CSA） and Centre for Agriculture and Bioscience Abstracts （CAB Abstracts） after strict assessments by these two databases.

An Innovative Land Approach for Spatially Determining SDGs-Sustainably Governing German Spree Forest and Lusatia Region

In times of highest necessities for United Nations Sustainable Development Goals(SDGs)and acknowledging planetary boundaries,the need for understanding general global goals and regional to local strategic governing structures has to be supported while combining assessment,monitoring,governance approaches,together with landscape planning,land use based approaches,land system and sustainability science.The initial research embeds an incrementally worked out theoretical framework followed by applied research parts.The case studies and field data in the German Lusatia Region and inner part Spree Forest Region inhabit intrinsic drivers of finding ways over bridging deficiencies of theoretical and applied adjusted objectives and in this small excerpt mainly about the scale and planning level,instrumental flexibility deficiencies while transmitting global transformation needs to the regional,local planning level and backward(counter-current principle).Innovative instrumental assessment structures were created with a new approach of spatially determining SDGs for accelerated Climate Smart Planning(CSP)and Integrated Drought and Water Management(IDWM).This research supports processes around acceleration and assessment of climate change-,crises-related and sustainable development options while enhancing interdisciplinary sustainability science for gaining more regional land resilience.

Development of land use transitions research in China

With the introduction of the concept of land use transition into China,related researches have been carried out extensively in the past two decades,which enrich the knowledge of land system science.This paper describes the development of research on land use transitions in China from the perspectives of conceptual connotations,theoretical model,research methods,and research progress and prospects.With the in-depth investigation of land use transitions,the concept and connotations of land use morphology are developed and encapsulated as two kinds,i.e.,dominant morphology and recessive morphology.The dominant morphology refers to the land use structure of a certain region over a certain period of time,with features such as the quantity and spatial pattern of land use types.While the recessive morphology includes the land use features in the aspects of quality,property rights,management mode,input,output and function.Accordingly,the concept of land use transition is further developed,and the theoretical model of regional land use transitions is established.Thereafter,three innovative integrated approaches to study land use transitions are put forward,i.e.,multidisciplinary research framework for recessive land use transition,transect and horizontal comparison.To date,there have been 62 Ph.D.and 166 M.S.dissertations on the topic of"land use transition"in China.During 2002–2019,the National Natural Science Foundation of China has funded 48 research programs on the theme of"land use transition".As such,the Chinese scholars have adapted the concept derived from western literature to the situations and experiences in China.

土地系统多主体模型——理论、应用与建模框架

Land change science has become an interdisciplinary research direction for understanding human-natural coupling systems.As a process-oriented modelling approach,agent based model(ABM)plays an important role in revealing the driving forces of land change and understanding the process of land change.This paper starts from three aspects:The theory,application and modeling framework of ABM.First,we summarize the theoretical basis of ABM and introduce some related concepts.Then we expound the application and development of ABM in both urban land systems and agricultural land systems,and further introduce the case study of a model on Grain for Green Program in Hengduan Mountainous region,China.On the basis of combing the ABM modeling protocol,we propose the land system ABM modeling framework and process from the perspective of agents.In terms of urban land use,ABM research initially focused on the study of urban expansion based on landscape,then expanded to issues like urban residential separation,planning and zoning,ecological functions,etc.In terms of agricultural land use,ABM application presents more diverse and individualized features.Research topics include farmers’behavior,farmers’decision-making,planting systems,agricultural policy,etc.Compared to traditional models,ABM is more complex and difficult to generalize beyond specific context since it relies on local knowledge and data.However,due to its unique bottom-up model structure,ABM has an indispensable role in exploring the driving forces of land change and also the impact of human behavior on the environment.
