中文摘要：
瞄准为生物多样性的有效保护提供理论基础，学习介绍联合质、量的方法的一个串联方法，与 RS (遥远的感觉) 合并基本数据技术，和等级生态系统根据它在 Hebei 的生物多样性可持续性的能力省。结果显示为在 Hebei 省的保护的最重要的区域是在在 Xiaowutai 山， Wuling 山，北方 Hebei， Taihang 山和东方 Hebei 附近的一些高地的森林和草地生态系统；草生态系统部分地高原区域和北方 Hebei；并且一些在平凡、沿海的区域散布了沼泽地。这个方法对当数据不空间地足够或不均匀的分布式时，特别承担大规模调查合适。
英文摘要：
Aiming at providing theoretical basis for effective protection of biodiversity, the study presents a cascade method which combines both qualitative and quantitative methods, incorporates basic data with RS（remote sense） technology, and ranks the ecosystems according to its ability of biodiversity sustainability in Hebei Province. The results indicate that the most important areas for protection in Hebei Province are forest and meadow ecosystems in some highlands around Xiaowutai Mountain, Wuling Mountain, North Hebei, Taihang Mountain and East Hebei; grass ecosystems in part of plateau area and North Hebei; and some scattered wetlands in the plain and inshore areas. This method is suitable for undertaking large-scale investigations especially when the data are not adequate or unevenly distributed spatially.
