摘要:
基于长江中游荆南三口河网地区生态系统特征，从自然生态条件、资源利用与环境保护、社会经济与发展3个方面，构建生态系统健康评价指标体系，运用模糊综合评判法对其2001—2014年的生态系统健康状况进行了评价分析。结果表明：近14年来荆南三口河网地区生态系统健康处于亚病态—一般健康状态，整体波动向好发展，脆弱的自然生态条件是关键性制约因素；受区域降水和长江来水双重影响，地区水文水资源情势复杂，自然生态健康水平长期在0.6上下波动，健康状态在亚病态和一般健康之间交替变化，提升水资源稳定性至关重要；资源利用与环境保护健康水平显著提升，由2001年的0.290提高到2014年的0.742，健康状态由病态发展到一般健康状态，但水资源开发利用率长期处于40%以上的较高的水平，水资源优化配置及集约利用有待加强；社会经济发展态势较好，健康水平由2001年的0.362稳步提升到2014年的0.819，健康状态由病态发展到亚健康状态，但城市化水平稍低，城乡收入差距偏大，仍需对城乡统筹发展问题给予高度重视。
Abstract:
In order to analyze the ecosystem characteristics of the three outfalls river system region in the middle reaches of the Yangtze River, three aspects including natural ecological conditions, resource utilization and environment protection, social economy and development were selected to construct the ecosystem health assessment index system. The fuzzy integrated evaluation method was used to evaluate and demonstrate the ecological health status in this region from 2001 to 2014. The results showed that: (1) the ecological health status of this region was inferior and in the sub-pathological or the fair healthy state in 2001—2014, the overall situation was fluctuating but increasingly better; the inducing factor of this status was the vulnerable natural ecological conditions; (2) the combined effect of these factors caused the status of hydrology and water resources in the area was complicated, the fluctuation of natural ecological health level was at the score of 0.6 for a long period and the health state alternated between sub-pathological and fair healthy state; thus, improving the stability of water resources was the key issue to be solved urgently in this region; (3) the health level of resource utilization and environmental protection increased significantly and the health score improved from 0.290 (the worst health state,) in 2001 to 0.742 (fair health state) in 2014; however, the exploitation and utilization rate of water resources in the area had been at a relatively high level above 40% for a long time; therefore, optimizing distribution of water resources and the intensive utilization of resources should be emphasized; (4) the momentum of social and economic development was favorable; the health level was improved from the worst health state (0.362) in 2001 to the sub-healthy state (0.819) in 2014. However, the level of urbanization was slightly lower, the income gap between urban and rural was still large and the attention should be paid to overall development of urban and rural areas.
