【摘要】：以土地利用生态适宜性评价结果指导区域土地利用模式,可以有效保障区域土地利用生态安全。论文利用GIS分析方法,选取高程、坡度、土地利用类型、土壤侵蚀状况、距风景名胜区距离、距水体距离、距道路距离、距居民点距离8个评价因子,对赞皇县土地利用生态适宜性等级进行划分,结果表明,赞皇县土地利用生态适宜性水平较高,土地利用适宜和较适宜区面积为506.23 km~2,占总面积的61.2%;较不适宜区和不适宜区面积为194.42 km~2,占总面积的23.5%。不适宜区和较不适宜区内工矿用地面积为0.9 km~2,需要调整用地属性,一般适宜区内工矿用地面积为0.9 km~2,需要限制建设项目类别、规模和建设范围。赞皇县现有的非金属矿采选业、化学原料和化学制品制造业是工业结构优化的重点。
[Abstract]:The results of land use ecological suitability evaluation can guide the regional land use model, which can effectively guarantee the regional land use ecological security. In this paper, using GIS analysis method, eight evaluation factors are selected, such as elevation, slope, land use type, soil erosion, distance from scenic area, distance from water body, distance from road, distance from residential area. The grade of ecological suitability of land use in Zanhuang County was divided. The results showed that the level of ecological suitability of land use in Zanhuang County was high. The area of suitable and more suitable area for land use is 506.23 km2, accounting for 61.2% of the total area, and the area of less suitable area and unsuitable area is 194.42 km mm2, accounting for 23.5% of the total area. The area of industrial and mining land in unsuitable area and less suitable area is 0.9 km / m ~ (2), which needs to be adjusted. Generally, the area of industrial and mining land is 0.9 km / m ~ (-2) in suitable area, and the category, scale and scope of construction project should be limited. The industry of chemical raw materials and chemical products is the focus of industrial structure optimization in Zanhuang County.
