石漠化是指西南湿润岩溶地区,在脆弱的岩溶地质基础上,由于不合理的人为活动参与岩溶自然过程,造成植被退化、水土流失,导致岩石大面积裸露,形成的一种荒漠化生态现象,是水土流失的终级表现。生态环境是人类生存和发展的基本条件,是经济社会进步的基础。石漠化是贵州晴隆县的灾害之源、贫困之因、落后之根。近年来,有关部门通过开展退耕还林还草、林草结合的治理方式,遏制了晴隆县石漠化的扩展,同时有效地提高了广大人民群众的经济收入,达到了生态效益和经济效益双丰收。“退耕还林、还草,林草结合”是解决喀斯特岩溶山区人地矛盾突出、治理石漠化和经济创收的有效途径。
Rocky desertification refers to the wetland karst area in Southwest China. On the basis of fragile karst geology, due to unreasonable human activities, it participates in the natural process of karst, resulting in vegetation degradation, water and soil erosion, resulting in a large area of rock exposed, forming a desertification ecological phenomenon, Is the ultimate performance of soil and water loss. The ecological environment is the basic condition for the survival and development of mankind and the basis of economic and social progress. Rocky desertification is the source of disasters in Qinglong County, Guizhou Province, the cause of poverty and the root of backwardness. In recent years, the departments concerned have stopped the expansion of rocky desertification in Qinglong County by carrying out the policy of returning farmland to forests and grasslands and combining forests with grasslands, and effectively raised the economic income of the broad masses of the people and achieved ecological and economic benefits Double harvest. “Returning farmland to forest, grassland, forest and grass combined ” is an effective way to solve the contradiction between man and land in Karst karst mountains and to control rocky desertification and economic income.
