摘　　要：基于InVEST模型的生境质量模块,采用2017年安徽省有关数据,定量评价了全省和生态保护红线内生境质量指数及空间分布。结果表明:由于红线内的生境退化风险较低,使得红线内生境质量指数远高于全省平均值,占全省国土面积15.15%的红线,生境质量指数总和占全省的26.54%。皖西皖南山区和沿江沿淮湖泊湿地区的红线斑块生境质量指数普遍较高;沿江5市城区周边、沿淮蓄滞洪区、砀山和萧县林区、阜阳城区周边以及六安至合肥的淠河-滁河干渠的红线斑块生境质量指数则相对较低。保护空缺指数较高的县(市、区)为皖南山区的旌德县、祁门县、宁国市和休宁县以及皖西山区的岳西县、太湖县和潜山市,建议结合生态补偿政策,有条件的将高生境质量人工商品林逐步调整为生态公益林增补进红线,以更好地维护国家和省域生态安全。Based on the habitat quality module of Invest model and relevant data of Anhui Province in 2017, the hab itat quality index and spatial distribution in the whole province and Eco-redline region were quantitatively evaluat ed. The results show that the habitat quality index in the Eco-redline region is much higher than the provincial aver age due to the low risk of habitat potential degradation. Accounting for 15.15% of the total land area of the province, the total habitat quality index of Eco-redline region accounts for 26.54% of the province. The habitat quality index of Eco-redline patches is generally high in the mountainous areas of West and South Anhui and the wetland and lakes along the Yangtze River and Huaihe River;The habitat quality index of Eco-redline patches is relatively low in the surrounding areas of five cities along the Yangtze River, the flood storage and detention areas along the Huaihe Riv er, the forest areas of Dangshan County and Xiaoxian County, the urban areas of Fuyang, and the main canal of the Pihe-Chuhe River from Lu'an to Hefei. Jingde County, Qimen County, Ningguo City, Xiuning County in the moun tainous area of Southern Anhui Province as well as Yuexi County, Taihu County and Qianshan City in the mountain ous area of Western Anhui Province with higher conservation gaps index. It is suggested that the planted commercial forest with higher habitat quality should be gradually adjusted into the ecological protection forest and added into the Eco-redline region with the ecological compensation policy support, so as to better maintain the national and provin cial ecological security.
