Health Assessment Of Life Community Of Mountains,Rivers,Forests,Farmland And Lakes Surrounding Lake Hongfeng

Life community of Mountains,rivers,forests,farmland and lakes was putted forward since 2013,has attracted public attention.First round of pilot restoration projects of life community of Mountains,rivers,forests,farmland and lakes have been published.It is a kind of ecological holism,emphasizes mountains,rivers,forests,farmland and lakes all compose one life community,if we manage them separately,attend to one thing and lose another.Lake Hongfeng is one of the drinking water resources of Guiyang city and the largest artificial lakes of Guizhou.Karst area occupied more than 80% surrounding Lake Hongfeng,where is large relief of topography,thinner Soil Layer,and large population,that lead to poor land carrying capacity,severe rocky desertification,water source distribution too dispersed too difficult to be used,the contradiction of grain demand.Ecological environment is fragile,easily damaged and not easy to recover.Healthy community life of mountains,rivers,forests,farmland and lakes of Lake Hongfeng is crucial to Ecological security and water security.in Guiyang.The Guian new area which is the eighth National New Area in research area is developing.The health assessment of community life of mountains,rivers,forests,farmland and lakes is of great significance to balance the new city construction and the development with regional ecological sustainability and maintenance work.Lake Hongfeng surroundings are the study which is a typical karst area.It includes Qingzhen city and Pingba district.The established health evaluation model of life community is H=S*C,where;H is the health index of community life.S is the basic state index of community life,describe the state of life community of mountains,rivers,forests,farmland and lakes,C represents the coordination index how different subjects(mountains,rivers,forests,farmland and lakes)match needs of people,references ecosystem health defined by Costanza.On the basis of geography,landscape,statistics and ecological integrity,GIS spatial analyze,statistical methods were used to process those data.And setting standards by referring to the domestic and international industry standards,literature to evaluate health of life community surround Lake Hongfeng in 2005,2010,2015.The driving forces of health state of life community were confirmed by analyzing the relation of the evaluation result,land-use and regional policies.Using the CA-Markov and the grey model predicted the health index of community life in 2020,2025,2030.In order to give advises to protect and restore life community of mountains,rivers,forests,farmland and lakes in Guian new area.The main research results of this paper are as the following:(1)The health index curve of life community of Qingzhen city and Pingba district is showed the "V" type from 2005 to 2015,the health index of life community is 10.80,10.19,11.34and10.13,9.59,11.56 which belong to sub-health,respectively.The basic state index of life community and forest,lake state index of correlation index is 0.92 and 0.96.The strong correlation with PAFRAC of woodland,drought-flood gradations and per capita water resources,that indicates harmonize relations of human and mountains,rivers,forests,farmland and lakes.The health index of Community life is infused by NPP,the water storage projec rate of water supply,fish production per unit area.Focus on cultivated land,forest land and unused land changes.(2)Around 2005-2015,the driving forces of the life community of mountains,rivers,forests,farmland and lakes include: extreme weather,karst landforms,policies,water conservancy,ecological protection engineering.Extreme weather causes disasters to my wife,influences the survival of plants,animals and environment,and destroys forest state and coordination.Karst limits basic state of life community.Agricultural policies have a powerful control to guide the planting structure,in this time frame,the per unit area yield of grain dropped,food gap got bigger,the life community coordination adversely affected.Water conservancy projects make full use of the advantages of lake and reservoir to solve the problem of water shortage in the region.After a number of ecological protection measures are implemented,regional ecological environment is improved.(3)Life community health of mountains,rivers,forests,farmland and lakes will still maintain sub-health level in 2020,2025 and 2030,which was simulated by CA-Markov and the grey model.Healthy index of life community of Qingzhen city and Pingba district are 10.83,10.76,11.58 and 11.36,11.50,11.62.Forestland,lake condition will be better,basic state index of life community will be increasing.Forest and lake state score of Qingzhen city should be greater than Pingba district,above 4 point.Pingba district water state remains the same,the area of drinkable water will becomes smaller in Qingzhen.The farmland state of both region declines.Except 2030 year,coordination index less than 2015 coordination index,because of cultivated land resources cannot meet the demand of increasing population.There are two problems-water quality and food security will trouble the study in the future.(4)Putting forward advices to repair he life community of mountains,rivers,forests,farmland and lakes that based on the results of the study in order to protect state and promote the coordination.The advices include five aspects which is environmental monitoring,water resource protection and utilization,the construction of disaster prevention,food production,land resources protection.
