| 摘 要： | 生态系统完整性不仅反映了环境干扰下生态系统维持最优化运作和良性发展的能力，也反映了为人类社会提供有价值产品和服务的能力。本文以生态系统完整性的视角，从耗散结构和生态系统结构、过程、服务功能方面分析了岩溶生态系统的特点，表明岩溶生态系统完整性也是潜在脆弱的，随着生态的逐渐退化，生态系统完整性逐渐损失。作为人类作用胁迫下的终态，岩溶土地石漠化的发生和加剧代表着岩溶生态系统完整性的丧失，石漠化治理及生态恢复过程则是生态系统完整性逐渐恢复的过程。

| Abstract: | Ecosystem integrity reflects not only the capability of maintaining natural balance or self - organization but also the capability of providing valuable products and service for human society. This paper mainly discussed the characteristics of the structural, process and the functional integrity of karst ecosystem through the ecosystem integrity point of view. It shows the karst ecosystem integrity is at a vulnerable status. The karst ecosystem integrity is gradually losing when the ecosystem degrades. The formation and succession of karst rock desertificafion, as the ultimate result of human negative activities, means serious loss of ecosystem integrity. |
