摘　　要：利用全国31个省(自治区、直辖市)2008年的县域数据,按照《生态环境状况评价技术规范(试行)》(HJ/T192-2006)的方法和指标,评价了全国县域尺度的生态环境质量状况,分析县域生态环境质量的空间分布格局。结果表明,我国县域生态环境质量以"良"和"一般"为主,占国土面积的72%;东部地区县域生态环境质量好于中西部地区,中部地区县域生态环境质量以"良"为主,西部地区则以"一般"为主;在空间分布格局上,各生态环境质量类型受气候、大的地形地貌影响明显,与重要的气候分界线、山脉分布具有很好的相关性。In the present work,we collected county-level data of 2008 of the 31 provinces in China,calculated county eco-environmental quality（EQ） index according to Technical Criterion for Eco-environmental Status Evaluation and analyzed the spatial distribution patterns of different types of eco-environmental quality.The results indicated that good and common was the two main EQ types,which covered 72% of China terrestrial area.Counties’EQ in Eastern Region was better than that in Middle and Western Region.good was the dominant type in Middle Region,whereas common in Western Region.Climate and landform is the main factor of affecting county EQ spatial distribution pattern.
