以海南省临高县域为评价对象,选取了灌溉、土壤TN、坡度等10项相关指标,构建了橡胶种植评价指标体系和评价模型,在此基础上运用GIS技术完成了橡胶种植多因子综合适宜性评价。结果显示:除去耕地、建设用地以及水域等当前不可更改的土地外,临高县有56 540.89hm2的土地适宜橡胶种植,其中高度适宜的土地面积2 666.15hm2,中等适宜的土地面积29 917.38hm2,临界适宜的土地面积23 957.36hm2。在所有可能更改为橡胶种植的土地中,仅有9.92%的土地不适宜橡胶的生长,这说明临高县在橡胶种植方面存在很大的潜力。
Taking Lingao County in Hainan Province as a research object,an evaluation index system and a model for suitability of rubber planting are established according to ten selected indexes including irrigation,soil TN,slope,etc.And on the basis of GIS technology,the paper makes land suitability evaluation for rubber planting not only with single factor but also with multiple factors.The results shows that apart from the farmland,construction area and water area,there are 56540.89 hectares of land for plantation of rubber in Lingao County,in which the highest suitability land,the middle suitability land,and the common suitability land cover 2666.15 hectares,29917.38 hectares,23957.36 hectares respectively.Only 9.92% of the land in the comprehensive evaluation area is not suitable for rubber planting,which indicates that Lingao County has a lot of potential land for rubber planting.
