Research Of Function Regulation Of The Landscape In Zhuzhou Area In Changsha,Zhuzhou,Xiangtan Ecological Green Cores

Ecological green cores at the junction of Changsha,Zhuzhou and Xiangtan,the development of great potential,but due to assume a more important ecological functions,greater protection demand,and therefore conflicts between protection and development of the outstanding,so protection situation is grim.We select ecological green cores of Zhuzhou area as a case study,the landscape structure and pattern change analysis as a starting point,based on geography,landscape ecology,urban planning,system science and other disciplines theory,by means of ArcGIS,Fragstats,Yaahp and other analysis software,through the dynamic changes of landscape structure,landscape ecological process change analysis to identify the landscape function,the construction of landscape function evaluation index system and evaluation model,and use the scenario analysis method to study the landscape under different scenarios and functional values,clarifies the direction of landscape function regulation and puts forward the corresponding measures of landscape function control scheme.The main contents and conclusions include:(1)Through the remote sensing technology and ArcGIS spatial superposition analysis technology to get landscape type space transfer situation.The results show that the transfer of landscape type is dominated by forest land and cultivated land,and the area of construction land is increased slightly.Grassland,water area and unused land are transferred to forest land,cultivated land and construction land;(2)The landscape pattern index was selected from the landscape type and landscape level,The results show that the distribution of patch types in the study area tends to be discrete,the degree of landscape heterogeneity is low,the number of plots of landscape types increases,and the degree of fragmentation of forest land,cultivated land and construction land in 2010-2014;(3)The landscape function is divided into three categories: ecological conservation,material production function and economic development function.Three levels of landscape function evaluation index system are constructed,and the index weight is determined by analytic hierarchy process.The evaluation model is obtained by combining multi-objective linear weighting function;(4)According to the situation of different land use,this paper puts forward three scenarios,such as ecological protection priority,industrial development leading and coordinated development situation,and points out the future direction of landscape function regulation,and puts forward the control measures and means from ecological planning,ecological engineering and ecological management respectively.
