Grey multiple objectives programming (GMOP) model based on China terrestrial ecosystem service value was constructed and applied to Lilin town. The result shows that GMOP model has more practical applicability and takes ecologic, social and comprehensive benefit into consideration. There are three programs after optimization. Program Ⅰ is comprehensive improvement and constructing ecological economy type, program Ⅱ is gross cultivated land dynamic balance type and program Ⅲ is compromise type. There are still problems in programs Ⅱ and Ⅲ, such as distribution in disorder, land left unused or abandoned. Based on the benefits above, Program Ⅰ>Program Ⅲ> Program Ⅱ. Program Ⅰ is the optimal case. Its comprehensive benefit is 8.43208×107 RMB yuan/a.展开更多

Differentiation in rural household behaviors and their consciousness in land use activities is widespread in rural China nowadays. It is important to understand the changing characteristics and laws of land use behaviors of rural households driven by their consciousness, so as to regulate their land use activities. In most empirical studies of land use change at rural household level, the land use consciousness, which acts directly on land use behaviors, is often neglected. In our research, the changes of land use behaviors of rural households are analyzed, through identifying how the land use consciousness affect the land use objectives, land management scales and land inputs of all the rural households in Bailin Village of Chongqing Municipality in the western mountainous China. Also, how the land use consciousness of different rural households comes into being under external stimuli is examined and the self-adjustment process of their consciousness according to their own conditions is also discussed. Finally, broad policy instruments are suggested to promote the rationalization of rural households′ land use consciousness and the standardization of their land use behaviors.展开更多

The boundary red line of urban growth, the red line of the number of basic farms and the ecology red line makes the local to conserve land. Land stock for village and town construction is a huge amount of potential resources. Redevelopment of land for village and town construction provides ensured land security for the smooth progress of urbanization. Combining village and town construction land use characteristics and making in-depth analysis of the difficulties in the redevelopment of village and town construction and its inner mechanism, policies and suggestions were proposed for the redevelopment of village and town construction land in terms of land property, land price, market allocation, planning, surveillance and so on, so as to provide valuable reference for the smooth redevelopment of village and town construction land, and the system design of villages and towns.展开更多
