Research On Assessment Of The Cultivated Land Intensive Use And Its Driving Factors In Guanzhong Region Based On "Press-State-Response" Framework

Land is the important foundation for human survival and social and economicdevelopment. Cultivated land as the essence of land is the important guarantee of foodsecurity, national security and social stability. Improve the utilization benefit of cultivatedland is the key of ensuring food security and realizing sustainable development. Therefore, tocarry out the evaluation of cultivated land intensive utilization has very important significanceto improve the comprehensive utilization benefit of cultivated land, achieve its intensive use,promote change in the pattern of cultivated land use and agricultural production.The article constructs the cultivated land intensive utilization evaluation index systembased on the PSR framework from the perspective of man land relationship, evaluates thecultivated land intensive utilization levels using entropy method and comprehensive indexmethod of Guanzhong area and its cities from2000to2009and analyzes the dynamicchanges of cultivated land intensive degree and regional differences. Through the qualitativeanalysis and quantitative analysis of the influence factors of intensive cultivated land use level,the article explores the main factors influencing the intensive cultivated land use level inGuanzhong area. Finally, the article proposes ways and measures to improve cultivated landintensive utilization in Guanzhong area and its cities based on the above analysisThe full text is divided into seven parts, the main contents are as follows:The first chapter is introduction. This paper expounds the research background, researchpurpose and research significance, summarizes and evaluates the domestic and internationalinterrelated research,and illustrates the research ideas and research methods.The second chapter is the cultivated land use description in Guanzhong area.It analyzesthe natural,social economic conditions,current situation and its changes of cultivated land usein this area.The third chapter established the index system and evaluation method. It establishedindex system based on the PSR framework on the existing research, determine the weight using the method of entropy.The fourth chapter analyzes evaluation results.The changes of the pressure index, stateindex, response index of cultivated land in Guanzhong region are analysed.The fifth chapter analyzes the driving force. Through qualitative analysis andquantitative analysis, it explores the impact of the main factors of cultivated land intensiveuse.The sixth chapter is conclusion and suggestion.According to the analysis result, it putforward the way to realize intensive utilization of cultivated land in Guanzhong region, andproposals to improve the level of intensive land use were put forward, finally the paper pointsout the deficiency of this paper.
