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。
Based on the assessment of Lingao County in Hainan Province, ten indicators such as irrigation, soil TN and slope were selected to establish the evaluation index system and evaluation model of rubber planting. On this basis, GIS technology was used to complete the multi-factor comprehensive and appropriate Sexual evaluation. The results showed that 56 540.89 hm2 of land in Linge County was suitable for rubber planting except for the current non-modifiable land such as cultivated land, construction land and water area, among which 2 666.15 hm2 were suitable for land use, 29 917.38 hm2 for moderately suitable land, The critical suitable land area is 23,957.36hm2. Only 9.92% of all the land that may be changed to rubber plantations is not suitable for rubber growth, indicating that Linxiao County has great potential for rubber plantation.
