Land Ecological Security Evaluation In Fuyu Country

Land is a fundamental what human beings rely on to live and develop. With the rapid development of economic and society, humans brings more and more pressure on land when chasing for economic benefit. Because of which, land ecological environment is seriously threatened. It results in many ecological problems such as soil erosion, land pollution, land desertification, etc. In this trend, land ecological security evaluation becomes the hotspot research of scholars from various countries. With the further in-depth research, evaluation methods and models increase day by day. But land ecological security evaluation is a complex process, and it is still in exploration stage. Methods of establishment and evaluation system is still a difficulty in the process of research, it demands more explore and research.This paper is based on data of <Social and Economic Statistical Yearbook of Qiqihaer>,<Statistical Yearbook of Fuyu County> and <Total Land Use Planning of Fuyu County>, which makes related analysis and research on its environment, social economic and land use state; forms the very index system for Fuyu county based on “P-S-R” model; uses entrpoy method to determine weight; use comprehensive index method to evaluate ecological security of Fuyu county by time from 2003 to 2012; analyses the result of evaluation and puts forward specific measures to promote ecological security construction.The result of research shows:In recent ten years, the overall ecological security of Fuyu county is in upward trend and has a large rise, which illustrates ecological security of Fuyu county has been improved a lot. But its ecological security was in a bad state and changed little during 2003 to 2007, resulting from chasing economic development and using lots of fertilizer, pesticide, mulch film, construction land expansion, loss in resolving soil erosion, etc. While land ecological security has an outstanding improvement from 2008 to 2012.It is inseparable from increased investment in environmental protection, the transition from first industry to tertiary industry, a higher level of modernization agricultural machinery what decrease pressure from human activities to land.At last, it puts forward methods of adjustment of land use structure and methods, improving industry structure, improving land intensification extend and utilization, implementing the relevant land policy and more to make benefits to ecological security construction of Fuyu county and make advice on how to make ecological security construction of Fuyu county develop sustainable.
