- Abstract:
- The types and the current distribution characteristics of rocky desertification in karst mountain area of northern Guangdong were analyzed to explore the causes and forming mechanism of rock desertification from the following aspects such as geological ground and form, hydrology and climate, soil and vegetation, population pressure, economic and social condition and land use, etc. It considers that the internal factor which leads rock desertification taking place is karst eco-environmental fragility, the backward economic and social condition and the irrational human activities are main influencing factors and driving factors. According to realistic situation of natural and social conditions and economic development in the karst mountain area in northern Guangdong, the three eco-economics improvment models are put forward: the improvment model of protective type, and the vegetation restoration model of eco-agriculture type, the replacement type of improvment model of non-agriculture industry.
