| 摘 要： | 本文在分析岩溶山区典型生态系统类型及其演化特征和岩溶水资源特点的基础上，通过湘西20年来的生态系统变化的对比，就其对岩溶水资源的影响进行了详细的论述。认为生态的恶化是引起岩溶石山区水资源短缺的一个重要因素，生态系统变化对岩溶水资源的影响主要是通过对岩溶水的补给、迳流、排泄等的影响，使岩溶水资源产生水质和水量的变化。明确生态系统变化是如何影响岩溶水资源的质与量这一重大问题，将有助于岩溶水循环机制的深入研究，为揭示岩溶水资源的形成、演化规律及控制机理，建立岩溶水资源评价、开发利用和保护的系统理论，探索岩溶水资源可持续利用模式提供科学的依据。

| Abstract: | Increasing anthropogenic activities are the most important factors causing changes in the environment. Based on an analysis of typical kinds of ecological systems and their evolutionary characteristics in karst mountain areas and the characteristics of the karst water resources, and by contrasting the changes in ecologic systems in 20 years in west Hunan, the effects of ecological systems on the karst water resources are discussed in detail in this paper. Degradation of ecological systems is considered an important factor in the lack of water resources in karst mountain areas, and changes in the ecological environment result in changes in quantity and quality of the karst water by affecting the recharge, runoff and drainage of the karst water. Understanding the important question of how the changes in ecosystems affect the quality and quantity of the karst water will be helpful in studying the mechanism of karst water circle. Thus, the scientific foundation will be laid for revealing the law and the control mechanism of the formation and evolution of karst water resources, for building a systematic theory of evaluation, exploitation and protection of karst water resources, and for exploring the sustainable utilization models of karst water resources. |
