Assessment of ecosystem services and economic valuation of bamboo-shaped ditches in typical red soil region of Southern China
摘要
Abstract
[Objective]The ecosystem services and econormic value of bamboo-shaped ditches in the typical red soil region Southern China were explored,in order to provide references for the value accounting of similar soil and water conservation measures,and to offer a basis for the promotion and application of bamboo-shaped ditches.[Methods]Taking Xingguo County,Ganzhou City,Jiangxi Province as the study area,the ecosystem services such as soil conservation,water conservation,carbon sequestration and sink enhancement,and mitigation of non-point source pollution and their values in a bamboo-shaped ditch were comprehensively analyzed through using a topographic survey,as well as through field investigations,sampling,and testing of physicochemical properties of the soil,and applying the alternative cost and market value methods.[Results]The soil conservation function and value at different slopes was highest at the top of the slope[74.86 Yuan/(m2·a)]in the bamboo-shaped ditch;the water conservation function and value was highest in the middle of the slope[5.16 Yuan/(m2·a)];the carbon sequestration and sink enhancement function and value was highest at the bottom of the slope[0.25 Yuan/(m2·a)];and the mitigation of surface pollution function and value was highest at the top of the slope[0.34 Yuan/(m2·a)].The total value of the ecological service function of the bamboo-shaped ditch varied at different slope gradients,specifically 78.63 Yuan/(m2·a)at the top of the slope,57.11 Yuan/(m2·a)at the middle of the slope,and 60.51 Yuan/(m2·a)at the bottom of the slope.[Conclusion]Bamboo-shaped ditch measures have important ecological service function values in the typical red soil region in Southern China,and different slopes show significant differences in the value of ecological service functions.关键词
