摘要
生态保护红线是维护国家和区域生态安全的底线。对于生态环境破坏严重的资源型城市而言,划定生态保护红线更是意义重大。以唐山市为例,通过生态调查和GIS空间分析相结合,划定唐山市生态保护红线,并结合划定过程对区域生态建设布局和发展方向提出建议。研究结果为:(1)生态保护红线理论计算面积为2 985.10 km2,占全市的21.03%;最终落地面积为1 383.02 km2,占全市的9.74%。红线区面积减少1 602.08 km2,占计算结果的53.67%,主要剔除了经济林、采矿区、矿产规划区。(2)生态修复与保护建议:一是保护生态功能极强的经济林区域,并对重点矿产开采区进行生态修复,建立河流生态廊道,面积分别为294.69 km2、227.26 km2、150.15 km2;二是加强生态监管,逐步完善公众参与制度。
The ecological protection red line is the bottom line to maintain national and regional ecological security. For the ecological environment of serious damage to the resource-based cities, the delineation of ecological protection red line is even more significant. In this study, taking Tangshan City as an example, through the combination of ecological survey and GIS spatial analysis method, the ecological protection red line in Tangshan was delimited, and the regional ecological construction layout and development direction were put forward. The research results indicate： （1） the theoretical calculation area of ecological protection red line is 2 985.10 km^2, accounting for 21.03% of the whole city; the final floor area is 1 383.02 km^2, accounting for 9.74% of the whole city. The area of the red line area decreased to 1 602.08 km^2, accounting for 53.67% of the calculation results, mainly excluding economic forest, mining area and mineral planning area. （2）Suggestions on ecological restoration and protection are as follows： first, to protect cological functions of the strong economic forest areas, and restore key mineral mining areas for ecology, meanwhile, to establish the river ecological corridor, an area of 294.69 km^2, 227.26 km^2 and 150.15 km^2 respectively; Second, to strengthen ecological supervision, and gradually improve the public participation system.
