The Spatial-Temporal Changes Of Grasslandlandscape And Trade-Offs Of Landscape Services Inxilin Gol League

Landscape is the most practical scale to understand and shape the relationship between human society and environment.From the perspective of landscape scale,which is based on the remote sensing data,GIS and Erdas imaging technology,the purposes of this paper are to analyze the spatial-temporal distribution of Xilin Gol grassland landscape in 2000 and 2010,to evaluate landscape services such as grassland yield,water conservation,soil conservation and carbon storage by the model of RUSLE and In VEST,and to balance the relationship of this four landscape services by using weighted sum of GIS and R language.Finally,the study area is divided into 3 ecological function zones.The results indicatethat:(1)The analysis of land use transition matrix shows that the arable land construction has decreased by 2.78%,woodland has changed a little,grassland has increased by 16.52%,water body has decreased by 43.37%;(2)The spatial distribution of grassland landscape and statistical analysisshow that grass yield,water conservation capacity,soil conservation capacity and carbon storage are on the up trend,the distribution characteristics is heterogeneity,and the biggest contributors are meadow steppe and typical steppe;(3)Within the scope of study area,four kinds of landscape services presented synergistic relationship.There are 3 ecological function zones being divided:? Eastern Steppe Ecological Economic Zone:The eastern area of East Uzhumuqin-West Uzhumuqin-The south area of Xilinhot-Zhenglanqi-Duolun County-Taibusqi;? Central Steppe Ecological Function Promotion Area:The western area of East Uzhumuqin-The north area of Xilinhot-Abag County-Baiqi-Xianghuangqi;and ? Western Steppe Restoration Conservation and Restriction Area:Sonid zuoqi-Erenhot-Sonid youqi.Through this research,the law of the spatial distribution of all kinds of landscapes types,and the sensitivity and problems of ecological environment are revealed to make a contribution in exploring the relationship between landscape service and landscape function,and to provide the scientific basis and data support for the comprehensive improvement of the ecological environment of temperate grassland in our country.
