摘要:
将四平市选为研究区域，根据有关文献，对适宜性评价因子进行选取以及确定其权重，再将 其分为四个等级。基于ArcGis 的分析识别模版，按照权重值大小对各评价因子进行叠加分析处理。 研究结果显示，Ⅰ级适宜性所占比例最大，近乎研究区面积的半数，为41.13%；Ⅱ级适宜性位居次席， 占总面积的29.89%；这表明四平市内大部分区域是适合进行农业生产的。Ⅲ级的面积为2927km2，Ⅳ 级面积为1223km2。Ⅳ级，也就是不适宜进行农牧生产的区域大多分布在四平市的东部及南部，要尽 量避免在此耕作。又从自然和人文两个方
Abstract:
Siping city was selected as the research area. According to the relevant literature, the suitability evaluation factors were selected and their weights were determined, and then they were divided into four grades. Based on the analysis and identification template of ArcGis, the evaluation factors were analyzed and processed superposition according to the weight value. The results showed that grade Ⅰ suitability, the larg? est proportion of almost half of the area in the study area, 41.13%; Ⅱ suitability ranked second, accounting for 29.89% of the total; This shows that most areas in Siping city are suitable for agricultural production. Ⅲ level covers an area of 2927 km2, Ⅳ level covers an area of 1223 km2. Ⅳ level, which is not suitable for agri? culture and animal husbandry production area is mostly distributed in siping in southern and eastern, try to avoid in the farming. The suitability distribution in Siping city is analyzed from two aspects of nature and hu? manity. The results can provide some references for the following agricultural and animal husbandry produc? tion planning.
