摘要:

湿地功能分区可更好地促进湿地生态系统的保护和湿地资源的可持续利用。本文以北京野鸭湖湿地保护区为研究对象,借助遥感技术从湿地生境的自然性、湿地物种的稀有性和人类活动对湿地的影响等,通过综合利用湿地普查、野外实测及气象等数据,重点分析生物多样性种类及分布、土壤类型及湿度、植被类型及长势、地表覆盖类型等功能指标的空间分异特征,以景观生态学和湿地科学理论为指导,运用GIS技术由空间叠置、相关分析和主导因子等方法,划分了湿地管育功能区和主导功能区。

Abstract:

Wetlands are considered as one of the most productive ecosystems on earth, and more vulnerable and sensitive compared to other ecosystems. With the development of the society, wetlands are suffering serious degradation and loss due to intense anthropogenic disturbance, such as wetland pollution, land use, etc. As one of the effective management measurements, regionalization of wetland function is helpful to have resources in a sustainable development pattern. This paper takes Widgeon Lake, in Beijing, as study region, combining with multi-source remote sensing data, wetland investigation, and the field and meteorological observation data, to analyzes natural features of wetland surrounding, rare feature of wetland type, rare feature of wetland species and the impact of human activities on the wetland. On the other hand, the species and species distribution, soil type and soil moisture, vegetation type and vegetation growing feature, soil erosion and land cover are analyzed, in order to implement regionalization of wetland. Consequently, based on the principles of landscape ecology and wetland science, the function division is conducted, and the leading function area is determined based on GIS technique and overlay analyses, correlation analyses, and leading index methods. As to the management district, according to the hydrological situation and the DEM, the supplement region and protection region are marked out firstly. Then the center, buffer and experiment regions are ascertained in the protection region. As to the leading function area, the protection region is divided into bird protection, vegetation protection, water environment, material supplement, recreation and service regions.
