为改善云贵高原南部岩溶区生态环境提供科学依据，以滇东南那洒至马街岩溶区16组不同时代的石灰土为本体，采用实地调查、采样和检测方法，结合应用地质累积和潜在生态危害指数法研究云南东南部岩溶区石灰土金属元素对生态环境的影响。结果表明：P1y、Ch、Csd、D2d、Dd和 Dg石灰土的 Cd 为中度至重度级超标危害元素，∈2l石灰土的 Hg 为中度级危害元素，危害程度 Cd＞ Hg；Cd 对生态环境的影响明显，潜在的生态危害风险大；其他石灰土及相应元素则相对较安全，潜在的生态危害风险小。

In order to provide a scientific basis for improving the karst ecological environment in the southern of Yunnan-Guizhou Plateau,the authors took the calcareous soil in different age from the karst area in Nasa town ~ Majie town as samples to conduct the investigation,sampling,testing,and the geoaccumulation index method and the ecological risk index method were used for the influence of the heavy metals of calcareous soil to the environment and ecology.Results:Cd element is moderate to severe over standard in the P1y、Ch、Csd、D2d、Dd、Dg area,Hg is the harmful element at medium degree in ∈ 2l area, the harmful levels of Cd is far greater than Hg,the influence of Cd on the ecological environment is obvious,and the potential ecological risk is great;Other calcareous soils and the corresponding elements are relatively safe,the potential ecological risk is relatively low.
