【摘要】：[目的]随着人口的不断增加及城市化的快速发展,人地矛盾日益突出,土地等自然资源空间结构正在大规模转换。科学规划土地空间结构,在土地资源有限的前提下,合理分配土地资源,已成为区域可持续发展必须要解决的现实问题。[方法]采用GIS多因素叠加分析技术和土地利用适宜性评价模型,以土地利用类型、覆被动态变化为评价指标,采用层次分析法,确定指标权重,对河南省的土地资源空间进行适宜性评价。[结果]河南省漯河市、焦作市及洛阳市等地区的农业土地资源空间使用功能效率和农业技术发展水平相适应,土地适应性评价标准能够得到I等(S1)。河南省其他各市中的土地资源空间区划方面的优化空间较高,提高河南东部及北部的土地资源空间农业优化,能够提高河南省资源的使用效率。[结论]适宜性评价结果准确反映了河南省土地资源的实际情况,在制定河南省土地资源空间区划决策过程中发挥着重要作用,且对区域土地资源适宜性评价研究及提高土地资源空间区划的质量和效率提供一定的参考。
[Abstract]:[objective] with the continuous increase of population and the rapid development of urbanization, the contradiction between man and land is becoming increasingly prominent, and the spatial structure of natural resources such as land is changing on a large scale. Rational allocation of land resources has become a practical problem that must be solved in regional sustainable development. [methods] GIS multi-factor superposition analysis technique and land use suitability evaluation model were adopted to determine the type of land use. The dynamic change of mulch cover is regarded as the evaluation index, and the index weight is determined by AHP. [results] Luohe City, Henan Province, is used to evaluate the suitability of land resources and space in Henan Province. In Jiaozuo City and Luoyang City and other areas, the functional efficiency of space use of agricultural land resources and the level of agricultural technology development are in line with each other. The evaluation criteria of land adaptability can be obtained. The land resources spatial regionalization in other cities of Henan Province is relatively high, and the land resources spatial agriculture optimization in the eastern and northern parts of Henan Province can be improved. [conclusion] the results of suitability evaluation accurately reflect the actual situation of land resources in Henan Province, and play an important role in the decision-making process of the spatial division of land resources in Henan Province. It also provides a certain reference for evaluating the suitability of regional land resources and improving the quality and efficiency of spatial zoning of land resources.
