| 摘 要： | "京津风沙源治理工程"区植被恢复效果是该区生态环境研究的重点,其中地上生物量与净第一性生产力又是体现植被恢复效果的重要指标.本文对整个"京津风沙源治理工程"区的植被地上生物量与净第一性生产力进行调查计算,并将这两项指标在工程第一阶段实施前后的状况进行对比.结果显示:整个京津风沙源区植被地上生物量与净第一性生产力上升;植被地上生物量与净第一性生产力低的土地面积逐渐减少,地上生物量与净第一性生产力高的土地面积逐渐增加;区域内土地具有良好的植被恢复潜力与趋势.表明整个治理工程经过5年的努力,植被恢复取得一定治理效果.研究结果可为"京津风沙源治理工程"第二阶段提供基础数据及有益参考.

| Abstract: | The regional vegetation restoration effect of the Beijing and Tianjin sand source control project is the crucial part of ecological environment research in these areas.Important indexes used to show the regional vegetation restoration effect are aboveground biomass and net primary productivity.These two indexes have been surveyed and computed,and the dates of original have been comparison with the ones which have been computed after the implementing of the first phase of the project in this article.The resu... |
