【摘要】 以县级行政区域为评价单元,利用现有文献资料和补充调查数据,按照《区域生物多样性评价标准》(HJ 623—2011)规定的评价指标和方法,评价了山东省120个县级行政区域的生物多样性状况,分析了生物多样性状况空间分布规律。评价结果表明:山东省县级行政区域生物多样性指数在23.27～40.24之间变化,县级行政区域生物多样性状况分为"中"和"一般",分别占山东省土地总面积的55.8%和44.2%。鲁中南山地丘陵区和鲁东丘陵区的生物多样性状况好于黄河三角洲、鲁西北和鲁西南平原区。更多还原

【Abstract】 Taking the county-level administrative area as the evaluation unit,using the existing documents and supplementary survey data,according to the Standard for the Assessment of Regional Biodiversity(HJ623—2011),we evaluated the biodiversity of 120 units in Shandong Province and analyzed the spatial distribution of biodiversity.The results show that: the biodiversity index of evaluation units varies from 23.27 to 42.24;The grades of biodiversity were "intermediate "and "average",which account for 55.8 % and 44.2 % of total land area of Shandong separately;The grades of biodiversity in hilly areas of Mid-south and Eastern Shandong are better than plains of Yellow River Delta、Northwestern and Southwestern Shandong.更多还原
