Integration of Coupled Hydro-ecological Modeling in Poyang Lake Watershed Based on Digital Watershed Platform

In order to study complex environmental and ecological problems of Poyang Lake it is necessary to integrate or modify various existing models including hydrological, biological, social economic and other models with GIS techniques. This paper firstly discuses the construction of digital watershed platform for Poyang Lake, which is an integrated GIS environment for spatial data pre-processing and post-processing as well as an important foundation of hydro-ecological simulation, and then presents the integrated framework of coupled hydro-ecological modeling for Poyang Lake watershed (CHEMPLW) and its main functional components. CHEMPLW includes three parts: basic geodatabase, watershed data processing tools, and hydro-ecological models, while hydro-ecological models consist of four subsystems which are socio-human subsystem, land use/cover subsystem, watershed environment subsystem and river-lake/biological subsystem. Finally the integration method using ArcObject and Visual Basic is given.

Developing an Integrated Framework for Sustainable Development of Poyang Lake Watershed

本文以鄱阳湖流域为例,所描述的流域可持续发展框架是一个基于流域系统理论和实践的生态系统模型.包括了三个主要的部分:(1)环境政策与规划;(2)地球空间信息系统;(3)社区发展与区域网络.框架将多个学科,如:流域生态学,环境规划,可持续发展与资源管理汇集一起,形成了一套综合的流域制图、模拟和监测的流域管理方法.;The framework for sustainable development of watersheds described in this paper is an ecosystem model capable of economic evaluation based on watershed systems theory and practice, by taking Poyang lake watershed as a case. This integrating framework proposed has three primary components (a) environmental policy and planning, (b) geospatial information systems, and (c) community development and regional networks. The framework unites disciplines like watershed ecology, environmental planning, sustainable development and resource management in the mapping and modeling and monitoring of the watershed to retain holistic approaches to integrated watershed management.
