| 摘 要： | 从怀九河小流域生态系统的生态特征、地貌特征和水体特征三个方面入手,利用由22个定量指标组成的北京小流域生态系统近自然评价体系,对作为北京怀柔水库重要的入库河流-怀九河进行了实际评价。结果显示:怀九河17个小流域中仅有1个处于自然状态,6个处于近自然状态,8个处于退化自然状态,2个处于人工状态,总体受到了较大的人为干扰。并对评价结果进行聚类分析,结果呈现高度的一致性,为该体系的普及和推广提供必要的参考依据。

| Abstract: | From ecological,topographical and hydrological aspects,the near-natural assessment system of small watershed ecosystem of Beijing which is composed by twenty-two quantitative indicators have been used to make an actual assessment about Huaijiuhe River,which is one of the important interflowing river of Huairou Reservoir.The results showed that only one watershed is in the natural condition among seventeen ones,six watersheds are in the near-natural condition,eight watersheds are in the degraded natural cond... |
