| Abstract: | This paper selects the soil and climate resources, according to the previous research results and the expertise to determine the evaluation factor. Use the fuzzy mathematical method to quantify the evaluation factors, and then evaluated the planting suitability of rubber in Danzhou City by the method of principal component analysis. The results showed that the most suitable area for rubber planting is 43 029.58 ha, accounting for 14.99 % of the total agricultural land in Danzhou City; the suitable area for planting is 57 770.90 ha, accounting for 20.12 %; the less suitable area for planting is 40 934.9 ha, accounting for 14.26 %. The evaluation results not only bring the maximum benefit of the rubber at the macro, but also provide a reference for the zoning of the rubber plantations in Danzhou City. |
