| 摘 要： | 以贵州省长顺县石漠化综合治理区为研究对象,采用野外样地调查、室内统计分析的基础研究方法,对长顺县的石漠化综合治理工程区内的植被盖度、水土流失量和生物固碳量等核心生态效益指标进行了调查。结果显示,实施石漠化治理工程2年以来,工程区内植被覆盖度由原来的41.4%提高到62.4%,减少水土流失量1.46万t,生物固碳947.67 t,相当于多吸收空气中的二氧化碳3 474.79 t。石漠化治理工程的实施,既明显改善了当地的生态环境,又提高了农民的经济收入。对工程区内的林草措施实施人工管护,特别是应对灾害性天气的辅助措施,将有助于巩固治理效果,带来长期效益。

| Abstract: | With the comprehensive control area of stony desertification in Changshun County of Guizhou Province as the research subject,the fundamental research methods of sample plot survey and statistical analysis were adopted to investigate the core ecological benefits indices including vegetation coverage,soil erosion quantity,ecological carbon fixed quantity and so on within the comprehensive control area of stony desertification in Changshun.The results indicated that,in the 2 years since implementing the control project of stony desertification,the vegetation coverage in this area increased from 41.4% to 62.4%,water and soil loss decrease by 14 600 t,ecological carbon fixed quantity reduced by 947.67 t,equivalent to absorb 3 474.79 t of CO2 in the air.The stony desertification project significantly improves not only local ecological environment but also the economic income of peasants.The artificial management and protection of forest and grass,especially the auxiliary measures to cope with severe weather will be helpful to consolidate regulation effect and bring long-term benefits. |
