南方红壤丘陵区小流域水土保持综合效益评价——以江西阳坑小流域为例
Assessment on Comprehensive Benefit of Soil and Water Conservation in the Small Watershed of the Southern Red Soil Hilly Region——A Case Study in Yangkeng Small Watershed in Jingxi Province
摘要
Abstract
With more attention paid to the soil and water conservation in China,more and more soil and water conservation measures have been implemented.In order to evaluate the soil and water conservation work situation,soil and water conservation comprehensive benefits evaluation has become particularly important.We set 2005 as the base year and take Yangkeng small watershed,where the water loss and soil erosion are serious,in southern China's hilly red soil region as an example.We chose 13 evaluation indexes involving the ecological benefits,economic benefits and social benefits to analyze and evaluate the value of each single benefit,the three benefits and comprehensive benefits of soil and water conservation by market valuation method,alternative market price method,method of comparative analysis and so on.After soil and water conservation management in Yangkeng small watershed of Jiangxi Province,soil and water conservation comprehensive benefit values totaled about 124.454 2 million yuan in 2005.The ecological value was about 102.406 5 million yuan,accounting for 82.29％;single benefit value decreased in the order:the water conservation benefit＞the purifying atmosphere benefit＞the protecting fertilizer benefit＞the soil conservation benefit.Economic value was about 8.941 3 million yuan,accounting for 7.18％ single benefit value decreased in the sequence:grain production efficiency benefit＞the economic fruit forest benefit＞the soil and water conservation forest benefit.Social benefit value was about 13.106 4 million yuan,accounting for 10.53％;single benefit value decreased in the order:benefit of improving the economic＞benefit of improve land productivity＞ the benefit of add farmland ＞ benefit of reducing sediment deposition efficiency.We analyzed the single benefit ratio and the soil and water conservation of the three big benefits,and indicated that ecological benefit occupied the decisive position in the soil and water conservation work,which will provide theoretical basis for the work of soil and water conservation in the future,and at the same time,promote people to understand and pay more attention to soil and water conservation work.关键词
