农村聚落生态环境预警——以万州区茨竹乡茨竹五组为例

摘要

The authors define the concept of ecological and environmental warning on rural habitat ecosystem,put forward the indexes system and the indexes classification of environmental evaluation on rural habitat ecosystem. The environmental evaluation was made with the weight analysis method and the mathematical models and parameters of the warnings of environmental negative evolution was established.Choosing a typical habitat in the limestone mountain of Three Gorges Area as a case study,the authors make environmental forecasting and ecological warnings on the rural habitat ecosystem in the natural evolution status and in the regulating evolution status.%论述了农村聚落生态环境预警的概念，提出农村聚落生态环境预警评价指标体系和指标分级，运用加权平均模型进行环境评价，确立不良状态预警、负向演化趋势预警、恶化速度预警的数学模式与参数。选择三峡库区中低山石灰岩山地典型聚落作实例研究，对该聚落自然演替状态和必要调控状态的生态环境质量及演化趋势进行预测和预警分析。
