| description | The research on sustainable utilization of cultivated land eco-economic system has important practical significance for understanding cultivated land status and promoting sustainable utilization of cultivated land. Based on energy value theory and analysis method, this paper establishes the evaluation Index system of cultivated land eco-economic system in Yunnan Province, and chooses 5 main indexes, such as net energy output rate, environmental bearing ratio, system production dominance, system stability index and sustainable development performance index, etc. The energy input-output structure and sustainable development status of cultivated land eco-economic system were evaluated. The results show that the net energy yield of cultivated land system in Yunnan province is 0.29, lower than the national average, and the competitiveness of agricultural products is not enough; the system production dominance and system stability index are 0.51 and 0.68 respectively, which indicates that the system self-control, adjustment and feedback need to be strengthened, the environmental carrying capacity and sustainable development performance index were 0.66, 4.21, reflecting the province's arable land system in the sub-sustainable state. Therefore, the current agricultural development mode should be adjusted to optimize the input structure, and we should actively introduce external energy value, make full use of external resources, and relieve resource pressure. On the basis of applying agricultural science and technology, strengthening the utilization intensity of renewable auxiliary energy, developing green industry, reducing the environmental pressure on cultivated land system, realizing the sustainable utilization of cultivated land system. |
