房山区岩溶地貌是北方岩溶的典型代表,其中溶洞发育最多。通过野外调查共发现研究区内岩溶洞穴百余个,其中人可进入、规模较大且具有代表性的有20余个。这些溶洞在空间分布、地层岩性、地质构造、地貌以及洞体结构和形态上,具有一定的共同性。溶洞发育的地方,地下水富集度较高,因此也是岩溶地下水研究的主要途径之一。

Karst landform in Fangshan District is a typical representative of the northern karst, especially the karst caves are very developed. Through field investigation we found that there were more than one hundred caves, and about twenty ones that people could enter. These caves are similar in the respects of spatial distribution, lithology, geological structure, landform development, hole structure and morphology. The groundwater is rich where the karst caves concentrate. Meanwhile, the karst caves are also the main object to research the karst groundwater.
