摘要
以河北省山区为研究对象,利用全国第二次土壤侵蚀遥感调查数据、土地利用二次调查数据和DEM数据,依据生态修复的基本原理和方法,制成土地利用类型图、地面坡度分级图、海拔分布图等相关图件;采用空间叠置的相交工具及数据挖掘等方法,进行河北省山区生态修复的空间设计,并对河北省山区生态修复适宜性进行分区.研究结果表明:河北省山区可以分为2个大区、4个亚区、20个类型区.大区中适宜生态修复区面积为73 989.46 km2,在评价区和研究区所占比重分别为71.35%和60.20%;暂不适宜生态修复区为15 501.61 km2,所占比重分别为14.94%和12.61%;不适宜生态修复区为14 224.71 km2,所占比重分别为13.71%和11.57%.20种类型区中14种类型区可进行生态修复,根据采取的生态修复措施又可以分为5区.研究结果可以为河北省山区今后的生态修复工作提供科学依据,加快水土流失的防治步伐.
Using the second national soil erosion survey by remote sensing data, land use secondarysurvey data and DEM dataas well as basic principles and methods of ecological restoration, this paper,taking mountainous areas of Hebei Province as the research object, makes land use type map, ground slopeclassification map, and elevation distribution map. Through folding set intersect tool and data miningmethods, it conducts space design for Hebei Province mountainous ecological restoration, and partitions theecological restoration suitability in mountainous areas of Hebei Province. As the results show, mountainousareas of HebeiProvince can be divided into 2 regions, 4 sub-regions and 20 types of areas. The large areaof suitable ecological restoration is 73 989.46 km2, and proportion in the evaluated area and research areaare respectively 71.35% and 60.2%. The area which is not temporarily suitable for ecological restoration is15 501.61 km2, and the proportion respectively 14.94% and 12.61%. The area which is not suitable for theecological restoration is 14 224.71 km2, and the proportion respectively 13.71% and 11.57%. 14 types of20 types area can carry out ecological restoration, and according to the ecological restoration measures,they can be divided into 5 areas. The results of this study can provide scientific basis for Hebei Provincemountainous areas in the future ecological restoration work to accelerate the pace of the prevention andcontrol of soil and water loss.
