Abstract: The special geographical condition and climate have made rubber plantation become an advantage industry in Jinghong city. Since the reform and opening up, rubber planting area in Jinghong has been growing rapidly. Rubber cultivation has changed the agricultural industry structure and increased income level of farmers. Crop planting area decreases gradually, while rubber and tea cultivation show a rising trend. With the main crops cultivated area as the explanatory variable, we have conducted multiple linear regression analysis of the per capita net income, and concluded that regression fitting degree of rubber planting area and the farmers’net income is very high, with an increase of 10 000 hm2 in planting area adding 386 yuan to the per capita net income of farmers. The profit from tea cultivation is higher than that from rubber plantation, but because of soil, temperature, topography and other requirements, tea plant growth is significantly less than the rubber plantation. Per capita net income increase caused by rubber planting area increase accounts for 75.94% of the per capita net income increase since the reform and opening up. Spending on durable consumer goods shows higher correlation with rubber planting area, and its correlation with water output is 0.7045. The spending on consumer durables of townships with lower water output, such as Jingne, Mengwang, is also significantly lower than that of other villages and towns. Rubber plantation has improved people’s living standard, promoted development of transportation, water conservancy, education, expanded social communication range and changed the traditional means of livelihood, thus evoking secularization tendency of religious behavior. The change of forest into rubber plantation has weakened the function of climate regulation, and the climate in this area is changing from hot and humid to dry heat. During the past 30 years, the annual average temperature has risen by 0.8℃, and the average relative humidity has decreased by 6%. In addition, the necessary condition of biological survival has been destroyed and the biodiversity has lost, with species richness having declined by 60%. Ecological economic value of rubber forest(38 107 yuan/hm-2a-1)only accounts for 56.74% of the value of tropical rainforest and secondary vegetation. Correctly handling the relationship between rubber cultivation and economic development, social culture as well as ecological environment is an important issue for the sustainable development of minority nationality regions.
