中文摘要: |
退耕还林(草)综合效益评价指标体系的构建是退耕还林(草)工程效应评价的一个重要环节。首先根据黄土高原地区的自然环境现状和生态类型区划原则,将黄土高原划分为4个不同的生态类型区;然后根据综合效益评价指标体系建立的原则和方法,从生态、社会经济2个层次中选取对黄土高原影响较大的28个指标因子,建立适合黄土高原地区的退耕还林(草)综合效益评价指标体系;最后根据每个生态类型区的特征和自然状况,确定不同生态区域各评价指标的权重。 |
英文摘要: |
Establishment of the assessment index system of the returning farmland to forest project's multi-effect of Loess Plateau is a important part of the ecological effect assessment.According to the natural environmental condition and the ecological type area division principle of the Loess Plateau,the Loess Plateau should be divided into 4 different ecological zones.According to the principle and method of the establishment of the multi-effect assessment and also the influence of the returning farmland to forest project to Loess Plateau ecological environment,select 28 index factors which influent more to Loess Plateau from ecology and social economy levels,establish the assessment index system of the returning farmland to forest project's multi-effect of Loess Plateau,and then according to each ecological zone characteristic and natural condition,acquire the weight of each factor in different ecological zones of Loess Plateau. |
