通过对徐州市石灰岩低山丘陵地的野外调查，将其以坡度划分立地类型小区，以土被连续性划分立地类型组，以土层厚度划分立地类型，共分出3个立地类型小区，12个类型组和30个立地类型。结合前期调查所得结果分析得出，研究区30个立地类型均可通过运用适当的人工工程措施和生物措施进行综合治理，侧柏、五角枫、刺槐、乌桕、女贞、雪松、黄连木、楝树、火炬漆、全缘叶栾树、臭椿、柿树、朴树、构树、桧柏为石灰岩低山丘陵地造林适宜树种。

According to the field investigation, site subareas were classified by grade, site type groups by the continuity of the soil and site type by thickness of the soil at the limestone low mountains and hills in Xuzhou city. Thus, the area was divided into 3 site subareas, 12 site type groups and 30 site types. The investigation results showed that the above mentioned site types could be remediated by proper application of artificial engineering and biological measures. Meanwhile, the investigation results also showed that Platycladus orientalis, Acer mono, Robinia pseudoacacia, Sapium sebiferum, Ligustrum lucidum, Cedrus deodara, Pistacia chinensis, Melia azedarach, Rhus typhina, Koelreuteria integrifolia, Ailanthus altissima, Diospyros kaki, Celtistet randra, Broussonetia papyrifera, Sabina chinensis were suitable afforestation species. The results provided the theoretical guidance for the work of vegetation restoration and for the construction of water and soil conservation projects.
