- 摘要:
- 阐述了粤北岩溶山区石漠化的发展现状，从地质地貌、水文气候、土壤植被、人口压力、社会经济条件和土地利用等方面详细分析了粤北岩溶山区土地石漠化的成因及机理，认为脆弱的岩溶生态环境是土地石漠化形成的内因，落后的社会经济条件和不合理的人类活动是土地石漠化形成的主要影响因素和诱发因素。结合当地的自然、社会和经济发展的实际情况，提出了3种治理石漠化的生态经济模式，即保护型治理模式、生态农业型植被恢复模式和非农产业替代型治理模式。
- 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.
