黑龙江省生物多样性评价

摘要

This study collected the biodiversity data in Heilongjiang Province by field investigation and sample collection. The biodiversity is evaluated by comprehensive index based on research units of counties(cities). It is concluded that the biodiversity indexes of various counties(cities) in Heilongjiang range from 28.30 to 41.35. The biodiversity is divided into Medium level and Common level. There are 73 counties(cities) belong to Medium level, accounting for 95% of the whole province. Overall 9 coun- ties(cities) belong to Common level, representing 5% of the whole province.%采用资料收集与现场调查相结合的方法,获取黑龙江省生物多样性数据,以县（市）为研究单元,运用综合指数法对生物多样性进行评价。评价结果显示：黑龙江省各县（市、区）生物多样性指数为28.30～41.35,生物多样性等级分为＂中＂和＂一般＂两个等级。生物多样性等级为＂中＂的县（市、区）有73个,占全省国土面积的95%;生物多样性等级为＂一般＂的县（市、区）有9个,占全省国土面积的5%。
