中国南方喀斯特地区石漠化综合治理模式构建与技术支撑研究——以贵州省毕节市朝营小流域为例

Study on Model Construction and Technique Support of Rock Desertification Integrated Rehabilitation in South China Karst Areas—Taking Chaoying Catchment in Bijie City of Guizhou Province as an Example

贵州省毕节市喀斯特由于脆弱的生态环境和复杂的人地系统,加上历史上不合理的人为活动,使全市喀斯特地区生态环境严重恶化,出现了一系列重大的生态环境问题和社会经济问题,其中最显著的是生态环境遭破坏后形成的喀斯特石漠化。选取喀斯特发育和石漠化都具有典型性和代表性的毕节市朝营小流域为例,根据小流域喀斯特石漠化程度和所存在的生态环境问题,研究了朝营小流域石漠化综合治理的发展模式和技术支撑体系,提出了适宜毕节市乃至贵州省和中国南方喀斯特地区的石漠化综合治理发展模式与技术集成。

On account of flimsy ecology environment and complicated system of human and soil in the Karst area of Bijie City,and reasonless artificial action in the history,so ecology environment is deterioration badly,and appears a series of fateful environment problems about society and economy,the Karst rocky desertification is remarkable after environment went to pot.Selecting representative Karst rocky desertification as an example in Bijie City of Guizhou Province,the developmental model and technique support system of rocky desertification integrated rehabilitation in the Chaoying catchment was researched,the model and technique system of rocky desertification integrated rehabilitation was put forward,which is adapt to the Bijie City,Guizhou Province and South China Karst area.
