以桂林市岩溶塌陷研究为基础，提出了岩溶塌陷空间指数等密图的编制方法和原则。岩溶塌陷空间指数等密图不但能直观、定量地反映岩溶塌陷在平面上的分布强度和密度，面且能在一定程度上揭示诸影响因素对岩溶塌陷的控制作用，在岩溶塌陷风险评价和预测研究中具有重要的实用价值。
Based on the study of karst collapse in Guilin City, the method and principle for compiling isopycnic map of karst collapse are proposed. Isopycnic space index isopy maps not only can directly and quantitatively reflect the distribution intensity and density of karst collapse in the plane, but also can reveal the controlling factors of karst collapse to some extent. In the evaluation and prediction of karst collapse risk Research has important practical value.
