Research On The Evaluation Model Of Ecosystem Service Values And Its Application

Currently the values of ecosystem service research at home and abroad mainly formine natural ecological land systems to waters within the region, woodland, farmlandand other individual or integrated ecosystem for the study, assessment of ecosystemecology in the mine process dynamic changes in the value of the service. But mine isa special artificial-natural complex ecosystem, its value ecosystem service affecthuman social disruption and economic system,a simple function of the value ofecosystem service of natural ecological land systems to study the whole ecosystemservice values change mine has some limitations.Therefore,this article by constructingthe mine in Xuzhou Jiuli natural ecological land valuation model system service andsystem service construction land valuation model, considering the linkages betweennatural ecosystems and socio-economic systems, the study of the value of ecosystemservices in mine has important and far-reaching significance.In this study, Xuzhou Jiuli mine area is the research object. Using the surveymethod, RS method and csot method, according to the amount of coal mining processand the "three wastes" emissions levels and land use data in1995,2000,2005and2010, making mine unit area when the value of ecosystem services scale correction,based on the combined cost of ecological economics, research mine dynamic changesin ecosystem service values in the mining process. The results show that:(1) Ecosystem service values from1995to2010in Xuzhou Jiuli coal mine area is in agrowth trend from64.6159million yuan rose to87.4088million yuan,the mainfunction of natural ecosystems reflect mine for water conservation and wastemanagement,mine construction land ecological system service value losses decreasedafter the first rising trend,construction land mine system loss in value of ecosystemservice from123.224million yuan rose to144.5157million yuan from1995to2000,the values of the loss of ecosystem service were132.0536million yuan and110.682million yuan from2005to2010;(2) during the study period,the ecosystem servicevalues of Jiahe coal mine area,Pangzhuang coal mine area,Baoying coal mine areaand Wangzhang coal mine area have obvious spatial heterogeneity. Four minesecosystem service values overall trends are similar, but due to the impact of coalmining in the mine area and volume and other factors, the values of ecosystem servicePangzhuang mine the values of ecosystem service and natural construction landsystem is significantly higher than the other three mines;(3) ecosystem service values overall increased from1995to2010, ecosystem service values increased64.4693million yuan during the study period. The values trend of social service and culturalservice droped then increased. Environmental service values increased at38.417million yuan in2010, reflecting the good results achieved in mine environmentalgovernance.
