Due to overpumping groundwater, hazard of mantled karst collapse may often take place there.

因过量抽取地下水，造成覆盖型岩溶塌陷灾害。

The later period of karst corrosion deposit experienced lateritization, had accomplished the red clay basic characteristic.

岩溶残余堆物后期又经历红土化作用，造就了红粘土的基本特征。

The paleo-geomorphy before the sedimentary of the Permian formation is recovered with the Moulage method, then the karst geomorphy unit is partitioned.

采用印模法恢复出本区前的古地貌，划分出岩溶地貌单元，古地貌恢复表明，研究区古地貌总体表现为起伏不大，西高东低，相对高差最大约130米。

Moreover, two types of cements of limnic calcite and limnic dolomite and hydrothermal dolomite of reburial period are included in the karst rocks.

岩溶岩中发育有淡水方解石和淡水白云石2种胶结物类型，以及再埋藏期淀的热液异形白云石。

The karst depression belongs to the accumulative area of surface water and subdrainage area of subsurface water, the karstification is relatively week, and reservoirs are undeveloped.

岩溶斜坡和岩溶洼地为地表水汇集区及地下水排泄区，岩溶作用相对较弱，储层不发育。
