    摘要:

    贵州省是中国典型的喀斯特山区,喀斯特出露面积占国土面积的61.92%,石漠化现象严重,生态环境脆弱,生物多样性极易受到破坏。从生物多样性特征出发,从物种丰富度、生态系统类型多样性、植被垂直层谱的完整性、物种特有性、外来物种入侵度5个方面构建生物多样性综合评价指标体系,以县(区、市)为单元对贵州省的生物多样性进行综合评价,并将结果划分为4个等级。研究表明,评价结果为优的有10个县(区、市),占11.36%;评价结果为良的有29个县(区、市),占32.96%;评价结果为一般的有39个县(区、市),占44.32%;评价结果为差的有10个县(区、市),占11.36%。评价结果较好的区域主要集中在黔东北和黔东南的偏远山区,而评价结果较差的区域主要集中在地势较为平坦的黔中地区。

    Abstract:

    Guizhou Province is a typical karst mountainous area,accounting for 61.96% of the total exposed karst area in China.The rocky desertification in the region is serious,the ecological environment is fragile,and the biological diversity is especially vulnerable.Based on biological diversity,this paper established a comprehensive assessment index system of biological diversity using five indices of species richness,diversity of ecosystem types,completeness of the vertical stratification,species endemism,and number of invasive species.Using the established system,we evaluated the biological diversity of each county( districts,cities)for the entire Guizhou Province.The overall results were reported in four grades: excellent,good,average,and poor.There were 10 counties rated as excellent,accounting for 11.36% ; 29 counties as good,accounting for 32.96%; 39 counties as average,accounting for 44.32%;and 10 counties as poor,accounting for 11.36%.The regions with better grades are in remote mountain areas in northeast and southeast of the province,while the areas with lower grades mainly lies in flat terrain in central province.
