【摘要】：众所周知,随着中国社会的发展,城镇化进程的加快,人口与土地之间的矛盾越来越尖锐和突出,土地资源逐渐变成一种稀缺资源。中国是一个人口大国,人多地少,人均耕地面积不足世界的平均水平。如何合理的利用土地资源,提高土地的利用率,更加充分挖掘土地的潜力,成为当今社会研究的热点问题。论文基于GIS技术,通过建立黄岛区空间—属性一体化数据库,对黄岛区土地生产潜力进行了研究。在查阅总结前人计算土地生产潜力方法的基础上,针对研究区现状,选择了混合型模型(即光温阶乘模型)。对于土地生产潜力的研究,考虑到了光、气温、水分、土壤等各类环境因子的影响,通过对各类影响因子的逐步衰减,最终得到了黄岛区土地生产潜力值。同时,借助ArcGIS强大的空间分析及制图功能,得到了黄岛区各类生产潜力在空间上的分布特征,最终得到了以下结论:1、基于GIS技术研究土地生产潜力,更加高效准确,对影响土地生产潜力的各项因子能够考虑的更加全面。2、通过研究查阅前人的研究资料,研究了土地生产潜力的各类计算方法模型,选择了适合黄岛区的计算模型。对黄岛区土地生产潜力进行了各项综合分析探讨,对提高黄岛区土地利用效率,更加合理种植作物提供了科学依据。3、土壤条件是影响土地生产潜力的重要因子,论文采用层次分析法确定土壤有效系数计算模型中各指标权重,得出计算出的有效系数可靠性高。同时,能够依据土壤系数所计算出的土地生产潜力值,对黄岛区土地进行分级分区。4、黄岛区各乡镇街道各生产潜力值之间,总体相差不大,这是由于研究区面积较小,各项环境因子指标基本相同。同时,不同乡镇街道又有不同。近海的乡镇街道各项潜力值稍高,主要是因为光照强,所计算的光合潜力值大。黄岛区土地利用的总体水平较高。综上所述,论文的研究内容与结果,与现实情况基本一致,可以为农业规划发展提供一定依据,具有相关科学意义。
[Abstract]:As we all know, with the development of Chinese society and the acceleration of urbanization, the contradiction between population and land becomes more and more sharp and prominent, and land resources gradually become a kind of scarce resources. China is a large population, people, land, per capita arable land is less than the world's average level. How to make rational use of land resources, improve the utilization rate of land, and fully tap the potential of land has become a hot issue of social research. Based on GIS technology, this paper studies the potential of land production in Huangdao District by establishing the integrated database of spatial and attribute in Huangdao District. On the basis of reviewing and summing up the previous methods of calculating land production potential, a mixed model (namely light and temperature factorial model) is selected according to the present situation of the study area. Considering the influence of light, temperature, water, soil and other environmental factors, the potential value of land production in Huangdao area was obtained through the gradual attenuation of all kinds of factors. At the same time, with the help of the powerful spatial analysis and mapping function of ArcGIS, the spatial distribution characteristics of all kinds of productive potential in Huangdao District are obtained. Finally, the following conclusion: 1. Based on GIS technology to study the potential of land production, it is more efficient and accurate. The factors affecting the potential of land production can be considered more comprehensively. By consulting the previous research data, this paper studies all kinds of calculation models of land production potential, and selects the calculation model suitable for Huangdao District. The land production potential of Huangdao district is analyzed and discussed comprehensively, which provides scientific basis for improving land use efficiency and planting crops more reasonably. Soil condition is an important factor affecting land production potential. In this paper, the analytic hierarchy process is used to determine the weight of each index in the calculation model of soil effective coefficient, and it is concluded that the calculated effective coefficient has high reliability. At the same time, according to the potential value of land production calculated by soil coefficient, the land in Huangdao District can be divided into four zones. The difference between the potential values of production of each township and street in Huangdao District is not significant, which is due to the small area of the study area. All environmental factors are basically the same. At the same time, different villages and towns have different streets. The potential values of villages and towns near the sea were slightly higher, mainly because of the strong light intensity and the calculated photosynthetic potential. The overall level of land use in Huangdao is relatively high. To sum up, the research contents and results of the paper are basically consistent with the actual situation, which can provide a certain basis for the development of agricultural planning and have relevant scientific significance.
