粤北岩溶山区土地石漠化治理与农业综合开发模式研究

粤北岩溶山区是广东省石漠化土地分布的主要区域,经过多年的治理,土地石漠化出现了逐步逆转的态势,但石漠化仍是当地生态环境改善和社会经济发展的主要制约因素。在分析石漠化现状的基础上,依据当地不同的自然、社会和经济发展条件,提出了粤北岩溶山区、高原石漠化防治与农业综合开发模式和粤北岩溶丘陵、洼地石漠化防治与农业综合开发模式。把石漠化治理与农业综合开发密切结合起来,通过发展经济带动石漠化的治理。

Model for Rock Desertification Control and Agricultural Comprehensive Development in Karst Mountainous Area of Northern Guangdong

The karst mountainous area of northern Guangdong is the main distribution region of rock desertification in Guangdong province. Although the rock desertification land in this region is gradually decreasing due to controlling in the past years, the rock desertification is still the main restriction factor of eco-environment and social economy development. Based on the analysis of the present situation of karst desertification in northern Guangdong and according to the actual situation of natural, social and ecological development, this paper put forth the models for rock desertification control and agricultural comprehensive development in the karst mountainous area and plateau and in the karst hill and depression of northern Guangdong. The models aim to combine rock desertification control with economic development, and to promote rock desertification control by approach of developing economy.
