中文摘要	为了定量揭示西南喀斯特地区石漠化综合治理后的生态效益,以绥阳县典型喀斯特石漠化地区两条小流域(太白河和洪光坝小流域)为研究对象,基于野外试验、调查收集、实地验证、定点监测等手段获取数据,通过植物多样指数、国家林业行业标准(LY/T 1721-2008)、土壤流失方程(RUSLE)和社会经济评价指标体系对喀斯特地区石漠化综合治理效益进行评价.结果表明:①喀斯特石漠化小流域植物多样性指数、均匀度指数、物种丰富度指数增加,优势度降低;植被盖度增加,土层厚度不变,封育林枯枝落叶层增加,林地面积增加2 910.87hm~2.石漠化综合治理小流域植物群落逐渐复杂化.②小流域生物量和固碳量分别为19 550.52t和20 548.96t,以封育林的生物量和固碳量为主,固碳效益明显.③石漠化综合治理后小流域水土流失量减少611.25t.并且随着时间的推移,水土保持效益日益显著.④小流域农地生产力、农业产值、林业产值提高,人均纯收入增加,人民生活水平向小康发展.喀斯特地区石漠化综合治理后,其生态环境逐渐改善,固碳减沙效果明显,农民生活水平提高,对该区生态环境、区域经济、社会持续性发展具有极为积极的作用.
英文摘要	In order to quantitatively reveal the benefits of comprehensive control of rocky desertification in karst areas in southwest China,two small watersheds(Taibaihe watershed and Hongguangba watershed)in Suiyang of Guizhou,a county with typical karst rocky desertification,were taken as the research object.Based on the data offield experiment,investigation and collection,field verification,fixed location monitoring and other means,the benefits of comprehensive management of karst rocky desertification were evaluated with plant diversity index,the national forestry industry standards(LY/T1721-2008),soil loss equation(RUSLE)and the social and economic evaluation index system.The following results were obtained.① The plant diversity index,evenness index and species richness index increased and the dominance degree decreased in these watersheds after the efforts of comprehensive management;vegetation coverage increased,soil thickness remained unchanged,the litter layer became thicker in closed hills and woodland area increased by 2 910.87ha.Plant communities in the small watersheds of integrated control of desertification were becoming more and more complicated.② Carbon sequestration benefits were significant,biomass and carbon sequestrationin these small watersheds being 19 550.52t and 20 548.96t,respectively,owing mainly to the practice of closing hillside to facilitate afforestation.③ Soil and water loss decreased by 611.25t after comprehensive control of rocky desertification,and this benefit would become more and more significant.④ Farmland productivity,agricultural output value and forestry output value in the watersheds increased,and the per-capita net income increased.The living standards of the local people are moving towards a comfortable standard of living.
