| 摘 要： | 以景观生态规划的理论与方法为指导,针对三峡库区小流域生态系统的特点,在地理信息系统软件ARCGIS和ARCVIEW的支持下,对三峡库区小流域生态调控的空间途径进行了探讨.以重庆市开县石碗溪小流域为例,选择年均气温、土壤、植被、土地利用、高程、坡度、坡向、剖面曲率和平面曲率九个生态要素,综合运用生态敏感性与适宜性分析,结合景观格局整体优化的方法,对石碗溪小流域的景观空间布局进行了研究.通过生态调控的空间途径,将开县石碗溪小流域划分为农业景观功能区、生态恢复协调区和生态控制区3个分区,建立了3个分区之间以及分区内部的景观镶嵌组合关系,指出了各分区的产业发展方向.实践证明,以景观生态规划理论和方法为指导的生态调控的空间途径对三峡库区小流域生态经济系统的生态调控和功能的完善具有重要的实用价值.

| Abstract: | The torrents, distributed widely in the Three Gorges Reservoir Area, have heavily threatened water environment and ecological safety of the Three Gorges Reservoir because of their loss of soil and water, and are pivotal to resuming of eco-environments in the Three Gorges Reservoir Area. Therefore, ecological regulation of these torrents must be reasonably carried out and the resources of these torrents must be aptly configured. For analysis of the traits of ecological system of torrent,spatial approaches applied for ecological regulation of torrent in the Three Gorges Reservoir Area was discussed by means of the ARCGIS and ARCVIEW software based on the method and theory of landscape ecology. The spatial distribution of landscape in Shiwanxi torrent,Kaixian county,Chongqing municipality was investigated with an analysis of ecological suitability and sensitivity based on analysis of the nine ecological factors:average temperature,soil,vegetation,land use,elevation,gradient,slope aspect,profile curvature and Plane curvature. According to spatial approaches for ecological regulation of torrent, the Shiwanxi torrent was divided into three regions:functional region of agricultural landscape,ecologically resuming and harmonious region,and ecologically controlling region. The inlaid combination of landscape was set up among and within three regions and development direction of industry in the three regions was put forward accordingly. The reasonable steady ecosystem could be set up with the holistic optimizing of the landscape structure of torrent. The spatial approaches for ecological regulation based on the method and theory of landscape ecology has a great significance for ecological regulation of torrent in the Three Gorges Reservoir Area. |
