摘要
王家沟流域是晋西水土流失综合治理的典型样板之一。利用生态经济评价中经典的市场价值法和机会成本法对该流域的坡改梯和筑坝淤地等工程治理措施的经济效益进行了定量分析。结果显示 :这些工程措施使谷子、马铃薯、高粱、黄豆和玉米等粮食增产价值 2 7万多元 ;保水和保肥的价值为 19万多元。
Wangjiagou watershed is one of the examples of comprehensive control of soil erosion in western Shanxi.Using classic Market-Value Method and Opportunity-Cost Method,it quantitatively analyses the economic benefits of engineering projects,which increase the production of food and conserve water and fertilizer.The result shows that the increasing of food and conservation of water and fertilizer value over 270 000 and 190 000 RMB respectively.
