Abstract: Evaluating the coupling and coordinated development of land eco-economic system is helpful to reveal the evolution law of man-earth areal system, and to promote the sustainable utilization of land resources. Taking Jiangjin, an ecologically sensitive area in the Three Gorges Reservoir area, as an example, this paper studied the coupling mechanism of land eco economic system and constructed an evaluation index system of the coupling and coordinated development of land eco-economic system. Then, we analyzed the coupling coordination development characteristics of the land eco-economic system in village scale based on the model of land comprehensive evaluation and coupling coordination degree model. The results show that the development of land ecosystem in Jiangjin district is in a bad trend, which shows the characteristics of low-level village space squeezing high-level village space, and the development of land ecosystem shows obvious spatial differentiation. The development of land economic system in Jiangjin district is in a good trend. But the development of land economic system has great spatial difference, both in village scale and urban-rural scale. The land economic system in the urban area is better than that outside the urban area, and the villages with good land economic system are basically concentrated in the urban area. The coupling and coordination development of land eco-economic system in Jiangjin District evolves in a favorable direction, which means that land eco system and land economic system are promoting each other. However, the overall level of coupling and coordination of land eco-economic system in the whole district still needs to be improved, because the coupling and coordinated development of land eco-economic systems in most regions are in the middle and low level and some villages are still in a state of maladjustment. The coupling and coordination development of land eco-economic system in Jiangjin district has significant spatial differences. The high-level villages are sporadically distributed, while the villages in medium and low level are widely distributed. The villages in maladjusted state are mainly distributed outside the urban area.
