TEMPORAL-SPATIAL ANALYSIS OF ECO-SYSTEM'S SERVICING VALUES IN DEQING COUNTY
Evaluation of eco-system's servicing values provides a vital basis for land resources allocation,eco-environmental protection,carbon trading and ecological compensation standard,also one of the hot topics in research academy.Estimation of countywide eco-system's servicing values based on grid is key to countywide quality development.This paper,based on a case study on Deqing county,Huzhou city,Zhejiang province,uses Deqing's 2010,2015 and 2020 land and economy data,using the method of material quality evaluation and its synergy and trade-off analysis to estimate Deqing's eco-system's servicing values,including their geographic distribution and temporal changes,and analyzes their correlation in Deqing and Deqing's townwide.Deqing's eco-system's servicing values reach to 3.033 7 billion CNY in 2010,3.590 6 billion CNY in 2015 and 3.880 6 billion CNY in 2020,a rising trend.On their geographic distribution,eco-system's servicing values in the western are higher central and eastern.Temporal changes of eco-system's servicing values in 2010,2015 and 2020 show a rising trend in Deqing's townwide.Correlation among Deqing's eco-system's servicing values shows a tradeoff relation between supply value and carbon sinking,oxygen releasing,water resources conservation,soil maintaining and organic matters producing,a synergistic relation among carbon sinking,oxygen releasing,water resources conservation,soil maintaining and organic matters producing in most Deqing's townwide.
