摘要:

土地资源的优化配置作为一种手段,其实质是依据土地类型本身的生态适宜性及其结构格局的差异性,运用人工技术调控的方法对有悖于自然生态结构的现状利用结构进行优化调整与安排,从而达到土地利用系统功能趋优的目的.论文首先从生态学的角度,根据黄河三角洲生态区划优化配置原则,对土地资源适宜方向与土地利用现状相匹配,甄别出需要调整的类型,构建黄河三角洲土地资源优化配置模型.其次基于该模型,利用GIS软件分析模块,实现土地资源优化配置.最后采用土地资源利用综合适宜度指数,对黄河三角洲土地资源优化配置效果进行评价,进一步说明了按照生态功能区划原则进行土地资源优化效果很好,具有一定的创新性.

Abstract:

The optimal allocation of land resources is one kind of measures, of which the essence is to judge the ecological suitability of land types and their structural difference. Artificial regulation technologies are utilized to adjust and arrange the structure of land use, which is different from natural ecological structure. Furthermore, land resources can be used in the best way and the region can be developed in a sustainable way. In the paper, according to the status quo of the Yellow River Delta (YRD), for the purpose of protecting and improving ecological environment, land use is arranged according to land suitability, and the results are used to optimize the allocation of land resources and to implement the optimal allocation of land resources in practice. Based on the model and using GIS, the land for cultivation is computed and analyzed, and its total amount is up to 2656.301 km2. Finally, a comprehensive suitability index of land use is referred and utilized, and the results show that the distribution rule of land suitability is that it increases gradually and symmetrically to the both sides of the current Yellow River channel. In a word, from the view point of ecology, it is comparatively reasonable for land resources to be optimally allocated according to ecological functional zones in the YRD.
