利用遥感技术、地理信息系统和全球定位系统对河北坝上实施生态农业工程建设后的生态效益进行了监测与评价。定量描述了坝上生态环境的动态变化趋势 ,并对坝上生态农业工程的气候效益、土壤改良效益、农业水文生态效益进行了分析与评价。研究结果表明 ,通过工程治理 ,使农业生态系统的功能增强 ,结构合理 ,取得了显著的生态效益。
With the help of remote sensing, geography information system, globe p osition system, the ecological impacts of Bashang Eco agriculture Project were monitored and evaluated. A qualitative description of the dynamics of the eco e nvironment was presented and the effects of Bashang Eco agriculture Project on the climate, soil water, and other ecological factors were analyzed and evaluate d. The results showed that the Bashang, after harnessed by Eco agriculture Proj ect, its system function had been strengthened up, and its structure tends to re ach rationalization , acquire the obvious ecology beneficial result.
