Progress on Effects of Land Use Change on Land Productivity

PAN Peipei 1,2,3,YANG Guishan 1,3,SU Weizhong 1,3(1.Nanjing Institute of Geography and Limnology,CAS,Nanjing 210008,China;2.Graduate University of Chinese Academy of Sciences,Beijing 100049,China;3.State Key Laboratory of Lake Science and Environment,Nanjing Institute of Geography and Limnology,CAS,Nanjing 210008,China)  
Land use/cover change(LUCC) is one of the hot issues of global changes.The impact of land use change on land productivity is an important part of effects of LUCC.Based on the concepts of land use change and land productivity,this paper summarizes the main research contents and methods mainly from the aspect of their impacts on the potential land productivity,food production capacity and soil quality.It also discusses the scales of impact in this study.Then,it further points out main problems in current studies.Finally,the paper suggests that future research should focus on the impact of land use changes in the structure,pattern and intensity on cultivated land productivity,especially in the range of small scale,and emphasize the application of spatial analysis,dynamic evaluation model and synthesis of scales.This article also puts forward that this research has become an inevitable strategic choice and it is of great significance to establish sustainable land use patterns and to ensure national food security.
