Estuarine Research, Monitoring, and Resource Protection
is principally designed as
a reference volume for estuarine and watershed scientists, resource managers, decision
makers, and other professionals who deal with coastal zone issues. Information
contained in this volume will be useful to individuals conducting either basic or
applied research on estuaries. It will also be valuable to administrators engaged in
coastal resource management programs.
Development of Geospatial Ecological Indicators in Jiangxi Province, China
Peng Guo and Xiaoling Chen
Comprehensive evaluation of ecological environments is necessary for environmental sustainability and management planning, which can provide quantitative documents as scientific guides for informed decision making. The existence of several environmental impact assessment (EIA) methods makes it difficult to make on an appropriate choice (Sankoh 1996).
It is widely accepted that irrigation allows for the increase and stability in agrarian
yields, being a necessary tool to support food supplies and necessities for certain raw
materials in the world. However, irrigated agriculture is also considered the most
significant fresh water consumer and one of the main causes of pollution, degradation
and depletion of natural resources. These impacts are primarily related to changes in
the water cycle, salinization of agricultural soils, and salinization and pollution of
water resources due to the use of agrochemicals....
Salt marsh is an emergent, interdial estuarine wetland system characterized by
persistent plant species such as cordgrass (
). Saltmarsh has
a fringe geomorphic setting, and the water source and hydrodynamics are predominantly
surface or near surface bidirectional flows.
The DSS will enable examination of existing conditions, forecasting of future conditions, and simulation of
alternatives that will be ecologically sustaining and socially desired. The DSS will address watershed, water
quality, water quantity, groundwater and ecosystem restoration needs at the small watershed, major
watershed, tributary river, and main stem Minnesota River reach levels of spatial scale. The DSS will
enable forecasting future conditions.
