【摘要】：根据低丘缓坡资源的适应性评价原则,科学合理的评价方法和评价因子,采用层次分析法和专家征询法确定研究区各评价因子的权重,建立土地适应性评价模型,以GIS的空间分析和统计分析功能为技术支撑,对研究区域内可开发利用的低丘缓坡资源进行适应性评价和分级。研究结果表明:利用GIS的空间分析技术,使得对刚性因子的处理更为直观快速,整个评价过程不仅是定量分析与定性分析的结合,还融入了定位分析的技术,使分析结果更加的准确和客观;另外,通过对研究区建设开发的适宜性进行评价,可以精确定位适宜建设区,大大降低了开发利用的风险及成本;研究区内一等适宜区仅占总低丘缓坡资源的4.85%,因此对其进行有效合理的开发利用显得尤其重要。
[Abstract]:According to the principles of adaptability evaluation of low hill and gentle slope resources, scientific and reasonable evaluation methods and evaluation factors, the weight of each evaluation factor in the study area was determined by AHP and expert consultation method, and a land adaptability evaluation model was established. Based on the spatial analysis and statistical analysis function of GIS, the adaptability evaluation and classification of the low hill and gentle slope resources which can be exploited and utilized in the study area are carried out. The results show that the spatial analysis technology of GIS makes the processing of rigid factors more intuitive and rapid. The whole evaluation process is not only the combination of quantitative analysis and qualitative analysis, but also the integration of positioning analysis technology. The analysis results are more accurate and objective, in addition, by evaluating the suitability of the construction and development of the research area, we can accurately locate the suitable construction area, and greatly reduce the risk and cost of development and utilization. The first class suitable area in the study area only accounts for 4.85% of the total low hill gentle slope resources, so it is particularly important to develop and utilize it effectively and reasonably.
