| Along with the accelerating process of urbanization,which inevitably disrupt the regional ecological security.Population,resource and environment problems are becoming more serious.Changsha-Zhuzhou-Xiangtan urban agglomeration is new type of industrialization in Hunan province's boot sector,is the construction of two social experimental zone.It's regional urbanization gradually accelerated,will inevitably lead to land landscape pattern changes.With increasing maturity and perfection of landscape ecology as well as the development and wide application of RS and GIS technology,a study on landscape pattern of land has beco me a landscape ecology,soil sciences and hot issues in the field of global change research done on the ecological landscape planning guide.In this paper,the application of RS and GIS technology,and through the Changsha-Zhuzhou-Xiangtan urban agglomerations in 1990,2000,1990 and 2014,four remote sensing data interpretation analysis,studied the land quantity change and change dynamic landscape type in the area,At the same time,using ArcGIS software spatial analysis and landscape pattern space analysi s technology,the changzhutan 24 years from 1990 to 2014 in the study area of land type changes,changes of landscape structure and landscape,this paper analyzes the influence factors,on the basis of the of changzhutan ecological landscape planning countermeasures are studied and discussed.The main content of this paper are as follows:Analysis of landscape structure and landscape dynamic change.By 1990,2000,2006 and 2014 four period remote sensing interpretation data,the dynamic change degree and transfer matrix model,analysis of the Changsha ZhuzhouXiangtan area 1990-2000 years,2000-2006 years,2006-2014 years and 1990-2014 years in four periods of landscape types use change,discusses the four different stages of change.Analysis of the changes of the landscape pattern of study area.With the help of ArcGIS software and Fragstats software,for 24 years the changes of landscape pattern in Changsha Zhuzhou Xiangtan area were analyzed by using landscape fragmentation,diversity,evenness and patch characteristics index.Analysis of influence factors of landscape pattern change research.Based on the analysis of the Changsha Zhuzhou Xiangtan of landscape structure and landscape pattern changes,from the aspects of natural factors,population factors,l ocation factors,policy factors and social economic factors of Chang Zhu Tan,the landscape pattern change in the study area were influencing factors.Analysis and research on the planning of ecological landscape.Based on the analysis of the changes of landscape pattern and landscape pattern changes,landscape type dynamic factors,discusses the Countermeasures of Chang Zhu Tan area ecological landscape planning. |
