Evaluation Of Ecological Land Of Yongtai County And Optimization

Since entering the industrial age,along with the growth of population and the continuous development of science and technology,human production and living with everlasting unprecedented scale and speed changing the natural environment and produce a series of unreasonable land use activities.Our country is in the phase of rapid urbanization,the land development and utilization of high density and a large amount of disorder,make the deterioration of the ecological and natural disaster in our country,the ecological environment security has become an important part of the country or regional security.In December 2010,the state council issued "the national development planning",YongTai county,as the key ecological function areas,study on ecological land use evaluation and optimization in YongTai county is the foundation of all the ecological protection and restoration in YongTai county,are essential to maximize ecological land in the area of ecological efficiency of a job.This paper takes YongTai county as the research object,using tools,such as the ArcGIS10.1,SPSS19.0 on summarizing domestic and foreign scholars to know,on the basis of connotation of ecological land use data of land use change,from the perspective of land ecological function of ecological land classification,so as to guarantee the ecological land can implement to the ground.At the same time,combined with previous studies,from two aspects of ecological service value and landscape structure characteristics of the study area of ecological land use evaluation,considering the major natural disasters are water loss and soil erosion in YongTai county,the ecological sensitivity of ecological land use has very big effect,so the superposition of terrain factors,build a comprehensive evaluation index system of ecological land use,comprehensive evaluation of ecological land in YongTai county,and put forward the ecological land use optimization scheme,in order to provide effective data for ecological land in YongTai county optimization and technical support,and also provide important reference for the construction of ecological civilization in yongtai county.Research results show that:(1)The research data of land use change data,rather than the remote sensing data,combined with the current status of land use classification standard,can guarantee the ecological land can carry out into the field,and with the national development planning,the main body function area planning in FuJian province more effective cohesion;(2)From the ecosystem service value,the landscape structure characteristic and terrain three aspects to construct the evaluation index system,can not only satisfy the general requirements of ecological land use evaluation,both their own characteristics in the study area,can be more comprehensive and objective reflect reality.(3)According to the research area of ecological land use comprehensive evaluation,the ecological land use in the study area is divided into three construction area.Ecological builting areas:low level of regional ecological security pattern,this area mainly includes ZhangCheng town,ChengFeng town,QingLiang town,and Ge Lin town some administrative villages,the township of,SongKou town,WuTong town,DaYang town,as well as the various industrial park and so on.Is the political,economic and cultural center in YongTai county,accounting for 5.52%of the total area of the study area;Ecological restoration area:namely the level of regional ecological security pattern,mainly including the PanGu town,the DaYang town,the XiaBa town,the TongAn town,is a major farming area,as well as the main planting areas of vivianlulu,tea,and tcamellia,accounting for 20.28%of the total area of the study area;Ecological conservation areas:namely the high level of regional ecological security pattern,the mountain provincial nature reserve area is mainly distributed in the cane,big ZhangXi water conservation ecological function areas,QingYun mountain scenic area,and soil and water loss areas and prone to geological disasters,accounting for 74.20%of the total area of the study area.
