| Abstract: | The area of karst hill in Guangdong Province is 1827 km2, the karst hill is vital to agriculture and environmental protection. In this paper, based on the field investigation and data analysis, we discussed the distribution region, area, features, land utilization status and problems of four kinds of the karst hill, including low corrosion hill, low corrosion-erosion hill, high corrosion hill and high corrosion-erosion hill in Guangdong Province. The results show that the distribution of karst hill in Guangdong Province is broad and scatter, they main locate in the north and west of Guangdong Province, account for 76% and 19%, respectively. There are many problems in utilization of karst hill such as disforestation and planting fruit tree as well as planting eucalyptus. For prevent karst environment from irrational exploitation, we suggest5 kinds of land utilization patterns for different area as follows. Ecologic forest + economic forests + economic crop in karst basin area, ecologic forest + firewood forests + economic plant in karst plateau area, corrosion-erosion hilly area-fast growing timber stands, ecotourism, mine area-ecological forest + mineral resources exploitation in karst beauty spot. |
