喀斯特生态治理区可持续发展能力评价——以贵州毕节鸭池、遵义龙坪、沿河淇滩示范区为例

为检验喀斯特生态治理区的治理效果，以贵州省毕节鸭池、遵义龙坪、沿河淇滩3个示范区为例，从资源承载力、环境支持力、人口发展与支持能力、经济发展能力、社会发展能力5个方面，选择45个单项指标，建立评价指标体系，采用“纵横向”拉开档次动态综合评价法，评价3个示范区2005、2007年的可持续发展能力。结果显示：空间上看，龙坪示范区的可持续发展能力最好，鸭池示范区次之，淇滩示范区最差；时间上对比，龙坪示范区和淇滩示范区的发展能力2007年比2005年有所提高，〖JP2〗鸭池示范区稍有退步。根据各示范区的主要人 地矛盾，提出控制人口、优化配置水土资源、加大林牧产业比重等对策，以提高其可持续发展能力，并为同类地区的可持续发展提供借鉴。

EVALUATION ON DEVELOPMENT SUSTAINABILITY OF ECOLOGICAL MANAGEMENT DISTRICT OF KARST AREAS——TAKING THE YACHI DEMONSTRATION AREA IN BIJIE CITY| LONGPING DEMONSTRATION AREA IN ZUNYI CITY| QITAN DEMONSTRATION AREA IN YANHE COUNTY| AS EXAMPLES

In order to test the governance effectiveness of ecological management district of karst areas，taking Yachi demonstration area in Bijie City，Longping demonstration area in Zunyi City，Qitan demonstration area in Yanhe County，Guizhou Province as examples，45 factors were chosen to build evaluation index system from five aspects including resources carrying capacity，environmental sustaining power，population development sustainability，economic development ability and social development ability，and using “vertical and horizontal” method，the development sustain abilities of the three demonstration areas in 2005 and 2007 were evaluated.The results showed that：From contrasting space，the development sustainability of Longping demonstration area was the best of all，followed by Yachi demonstration area，but Qitan demonstrationarea was the worst；From contrasting time，while the development sustainability of Yachi demonstration area was showed slightly backward，the Longping demonstration area and Qitan demonstration area were improved in 2007 than in 2005.Aim at the human land conflicts of the three ecological management districts，the article presented some contermesures to enhance its development sustainability，such as population control，optimal allocation of land and water resources，enlarge the forestry and animal husbandry proportion and so on，and provided the model on sustainable development for the similar karst area.
