Land Ecological Quality Assessment And Land Ecological Functional Zoning Of Xinxiang City

Land Ecological Quality Assessment can ef fectively evaluate the suitability,conditionality of social econom ic development for the utilization of land resources to human existence and the regional differences of land quality,to support the in-depth understanding of the ecologica l quality of the land and exp lore the capital precipitated land and other issues,in order to promote conservation and intensive use of land,while also providing technical support and refere nce value for the regional environm ental protection and econom ic development.Ec ological function zoning can provide a theoretical basis and direc tion for the developm ent of ecological environm ental protection as the sam e as scientif ic,rational and sustainable utilization of regional ecological environment.Meanwhile,according to differences in the focus of the d istrict distinguish between scientific conservation,management and construction,protection of ecological environment,suppressing ecological environ ment quality continued to deteriorate.In this paper,on the case of the Centra l Plains Economic Zone –Xinxiang City of Henan Province for an exam ple,from the vision of land m anagement and landscape ecology theory,and tak es full acco unt of the natural conditions and socio-econo mic conditions of Xinxiang City,based on the c onstructed index syst em of regional land ecological quality assessment.I collected th e relevant index data in the index system,using ArcGIS,Erdas,SPSS software for functiona l analysis of relevant data,in order to study the land ecological quality evaluation and land ecological f unction zoning of Xinxiang City,trying to build a green hom eland spatial pattern,a nd provide reference for the county and even the provincial land-use planning and management department.This paper mainly includes the following aspects:Firstly,Land Ecological Quality Assessm ent.I chose the 29 indicators which impact land ecological quality,building the f our aspects of norm s layer which include natural geographical f actors index in the index system.By Entropy m odel and comprehensive method to the village adm inistrative unit for evaluating the land ecological quality of Xinxiang City,Henan Province,was evaluated.The results show that: based on a comprehensive assessment of the value of Xinxiang City,69.9% of the land mass between ecological good,between excellent and comprehensive range of 0.57 to 0.74,located in Huojia County,Yuanyang,Yanjin County,Fengqiu Count y Changyuan other regions;Eastern of Fengquan district,Muye district Midwest,the results of the evaluation of ecological quality Weibin City area is poor,accounting for 2.34%,the integrated assessm ent value between 0.22 to 0.38;The rem aining 27.8% of the land is between the general ecological quality and moderate,integrated values ranging from 0.39 to 0.56.Research and analysis of complex evaluation showed that the spatial distribution of: natural and geographical basis,the level of urbanization,resource requirements is the most important factor in the role of controlling ecological quality of the land.Secondly,based on the result of land ecol ogical quality assessment,by the method of cold-hot spots analyst,special difference of land ecological quality was analyzed,and the study area was divided into four dif ferentiation type areas: high concentration area of low value,concentration area of low va lue,not obvious agglom eration area,high value agglomeration area.Based on obstacl e degree calculation m ethod,the main control factors of land ecological quality in each differentiation type areas was determined.On this b asis,the north of Huixian City,the north of W eihui region were divided into northern ecological tourist area;Xinxiang County,Xinxiang city,the south area of Weihui City and Huixian City is divided into urban developm ent ecological reserve area;Huojia County,YanJin County,north-central area of Yuanyang Country,north-central region of Fengqi u County were divided into ecological agriculture area;south part of Yuanyang Country,southern part of Fengqiu county,Changyuan County were divided into the Y ellow River wetla nd ecology nourishing ar ea.Each district covers an area of 1418.25 km~2,1939.3 km~2,2938.36 km~2,2071.23 km~2 respectively.
