九溪河小流域景观生态评价

Evaluation of Landscape Ecology of Drainage Areas of Jiuxi River

以九溪河小流域为研究对象,在二类调查资料和地理信息系统ARCGIS的支持下,以地貌和土地利用类型为基础,建立小流域景观生态分类系统,应用景观生态学的评价方法,选取自然性、多样性、恢复性、稳定性、生产力、宜人性、侵蚀度等7项评价指标,从景观生态格局、景观生态质量等方面进行综合评价。

In this paper,the drainage area of Jiuxi River was used as object of study.Under the support of secondary investigation resources and geography information system ARCGIS,using physiognomy and the land utility pattern as the basis,the paper established the landscape ecology classification system of the drainage area.Using the evaluation methods of landscape ecology,choosing seven evaluation standards such as natura-lness,diversity,restoration,stability,productivity,amenity and errosion,the paper carried out comprehensive evaluation from the pattern and quality of landscape ecology.
