【摘要】 为了克服以往在生态系统功能评价中不同研究对象,尤其是不同研究区域之间套用功能系数或打分评价的缺陷,提出了一种生态功能价值的等值换算方法,并以甘肃省靖远县永新乡退耕还林和荒山封育功能评价为例进行了实际运用。结果表明,该方法不仅克服了以往不同研究对象,尤其是不同研究区域之间套用功能系数或打分评价的缺陷,而且实现了在生态功能评价中不同生态功能与农作物产值的可比性,使之更为具体、准确。该方法可用于不同生态措施的价值评价,尤其适用了对国家退耕还林和公益林价值的评价。更多还原

【Abstract】 In order to overcome the deficiencies of different subjects, especially apply function coefficient between different research areas or evaluation by scoring in assessment of ecosystem function in the past, a method of equivalent conversion of ecological function value is proposed by an example of the evaluation function of farmland to forest and barren enclosure in Xinxiang forever of Jingyuan County of Gansu Province. The results show that: The method not only overcome the shortcomings of apply function coefficients or scoring evaluation between different subjects, especially between different research areas previously, and also achieve comparability of different ecological functions and crop production value in the ecological function evaluation, and make them more specific and accurate. This method can be used to evaluate the ecological value of different ecological measures, especially for the value assessment of returning farmland to forest and public welfare.更多还原
