specifically, based on the dynamic interaction relation between village construction and resource environment evolution, the utilization of the intrinsic resource and the environment background are basic supports for village construction and development, and the local resource environment bearing condition changes correspondingly along with the village construction and development. The village and town development and the change of the bearing capacity of the resource environment are taken as a whole, and the resource environment subsystem forms a typical open system through exchanging substances, energy and information with the village and town development subsystem. In the open system, the village construction condition and the change of the bearing capacity level of the resource environment are important characteristics of evolution, and the change of the relation between the village construction condition and the bearing capacity level of the resource environment is the representation of dynamic change of the village construction-resource environment system.
The embodiment aims at the village and town areas of China, the construction of the local area refers to judging conditions such as endowment of resources and development of industry, integrates resources such as water, soil, manpower and the like in the village and town areas, and is combined with the implementation of projects such as industrial cultivation and development, ecological conservation, cultural inheritance, infrastructure, public service facilities and the like, reconstructs ecological space, living space, production space and cultural space of the villages and towns, realizes the processes of clean living space, civilization of ecological space, intensification of industrial space and diversification of cultural space, and promotes scientific and long-term development of the villages and towns. Therefore, the construction level function and the resource environment bearing capacity function of the villages and towns in China need to be constructed in a targeted manner by selecting different index sets according to the resource endowments and the industrial development of the villages and towns. Factors which can be referred to the construction level function of the villages and towns in China are ecological space, living space, production space, cultural space and the like of the villages and towns; for the resource environment bearing capacity function, the construction steps comprise: firstly, determining the category (comprehensive category, agricultural category and ecological category in the embodiment) of a resource environment subsystem according to the dominant function type of villages and towns; and then determining a resource environment bearing capacity evaluation index for the resource environment bearing capacity function according to the classification. For example, for the comprehensive class, the resource environment bearing capacity evaluation index mainly includes items such as B1, B2, and B3.

Specifically, the coupling degree between the village and town construction subsystem and the resource environment subsystem is calculated according to the comprehensive index of the village and town construction subsystem and the comprehensive index of the resource environment subsystem. The specific expression of the coupling degree model of the two systems of the construction of the China villages and towns and the bearing capacity of the resource environment is as follows:
wherein C represents the degree of coupling (the value is 0,1]Within a range), μ 1 Is the comprehensive index mu of the village and town construction subsystem 2 Is a comprehensive index of the resource environment subsystem.
The degree of coupling can be divided into 6 types: when c=0, there is no coupling effect between the two subsystems; c epsilon [0,0.4] is a low level coupling state; c epsilon [0.4,0.6] is a coupling state of a middle level; c epsilon [0.6,0.8] is a higher level coupling state; c epsilon [0.8,1.0] is a high level coupling state; when c=1, the coupling coordination effect of the two subsystems is optimal, and the whole composite system reaches a benign running state.

wherein D is a coupling cooperative schedule; t is the development degree; c is the degree of coupling.
On the basis of judging the interactive coupling state of the construction of the villages and towns in China and the bearing capacity of the resource environment, the coupling coordination degree between the two subsystems is calculated to evaluate the coordination state of the two subsystems.
The coupling co-schedule may be divided into four classes:
when D is 0< and less than or equal to 0.4, the coupling is low-degree coordination coupling, which shows that the overall coordination effect or mutual contribution is low;
when D is 0.4< and less than or equal to 0.6, the coupling is moderate coordination coupling, which shows that the whole synergistic effect or contribution is in a moderate degree;
when D is more than 0.6 and less than or equal to 0.8, the coupling is highly coordinated, which shows that the overall synergistic effect or contribution rate reaches a higher degree;
when 0.8< D <1, extremely coordinated coupling is adopted, which shows that the overall synergistic effect or contribution rate reaches extremely high degree, namely mutual promotion and synergistic development.
