| 摘 要： | 岩溶地区具有独特的地质地貌，在人为干扰作用影响下很容易导致当地生态系统稳定性降低，生态环境恶化，产生水土流失和石漠化等一系列生态问题。重庆市岩溶区面积占全市总面积的51％，同样面临着一系列的生态环境问题。通过分析岩溶地区生态系统的结构脆弱性、过程脆弱性、功能的脆弱性和人为胁迫脆弱的表现，发现导致生态系统脆弱的原因主要是水文、地质、植被等自然因素和人口压力以及不合理利用等人为因素，针对这些原因为生态系统恢复和重建提供合理建议。

| Abstract: | Karst areas have unique geological landforms.The human disturbance can easily lead to a series of ecological problems such as,lower stability of the local ecosystem,environmental degradation,coming into being rocky desertification and soil erosion.Karst area in Chongqing accounts for about 51 percent of the total area.It is also in the face of the same ecological problems.The ecosystem frangibility includes structure frangibility,process frangibility,the function frangibility and man-made stress.Through the... |
