摘要
基于地理国情普查数据,利用PSR框架模型,以河南省太行山地生态区、伏牛山地生态区和桐柏大别山地生态区为研究区域,从生态压力、现状和响应三方面计算了研究区域内71个县、区的生态格局综合指数,结果表明28个县区生态格局评价结果为良好级别及以上,32个县区处于生态格局较差水平以下,11个县区生态格局指数级别在中等级别。整个生态区生态格局西部山区整体状况较好,东部丘陵平原地带尤其市辖区大部分生态格局状况较差。
Based on the data of geographical conditions and using the PSR framework model, the study calculated the ecological pattern index according to ecological pressure, ecological status and ecological response. The study area was in the key ecological region in Henan province included Taihang mountain ecological area, Funiu Mountain ecological area and Tongbai Dabie mountain ecological area. For the total 71 counties and districts, the results showed that the evaluation results of 28 counties and districts were good and above;the ecological pattern of 32 counties were in the poor and below grade;the ecological pattern index of 11 counties and districts in the middle-level. For the ecological pattern of the whole ecological region, the overall situation of the western mountainous areas is better than the eastern hilly plain especially the municipal districts.
