中国农牧交错带生态评价研究

Study on the cological safety assessment of farming-grazing transition zone in China

中国农牧交错带是我国农业种植区与草原畜牧区相连接的生态过渡地带,又称半农半牧区或生态脆弱带。农牧交错带是一个独特而重要的产业界面,是我国最大的气候、生态过渡带,在我国经济、社会发展和环境保护方面具有重要的战略地位。本文对中国农牧交错带生态安全评价的研究是以农牧交错系统特殊的生态状况为基础,考虑到现有的自然环境压力、社会经济压力以及人类的积极影响,选择目前与潜在的压力、对生态系统的影响以及经济社会的响应3个方面作为指标体系和评价标准,对中国农牧交错带生态环境因子以及生态总体状况进行安全评估。因此,根据农牧交错带的特点,基于压力状态响应概念模型,建立了生态安全评价指标体系,以及相应的选取标准,将为农牧交错带生态安全评价研究和生态环境管理实践提供理论基础。

The area between farming and animal husbandry is the ecological transition zone between traditional agricultural area and pastoral area in China. It is also called agro-pastoral area or ecological ecotone. It is very important in terms of the economic, social development, and the environmental protection in China. It is the China＇s largest climate ecological transition zone and the unique important interface among industries. Based on the special ecological conditions in this area and in consideration of the existing natural environment pressure, the socio-economic pressure and the human positive pressure, the economic and social response and the current and potential pressure on ecosystems were selected as the indicator and evaluation criteria to evaluate the ecological environment and the overall security situation assessment of the Chinese ecotone. So, based on the characteristics of farming-pastoral zone and the concept of pressure-status-response model, an indicator system for assessment of ecological safety and the appropriate standards was setup as the theoretic basis for the future research on assessment of farming-pastoral zone safety and management of eco-environment.
