Taking rural settlement Raosi Village in Hengduan Mountains as a case study, and on the basis of the synthetic research into the ecological process of the complex ecosystem, the study shows that energy costs of production, human living and ecology functions are separately taking 1.36%, 13.59% and 85. 05% of the gross ecosystem functions, and the exertions of production and human living functions are close to a high-point state on the present using level of energy in the settlement. The study also shows that the most important function of a rural settlement in mountain area is its ecological rather productive function.展开更多

Taking Shangluo City for example, problems in the spatial planning of middle- and small-sized mountainous cities were explored, it was stressed that local characteristics should be respected to make plans reasonably, and handle the spatial transition between urban and rural areas properly, so as not to lose the originality of rural areas during the urbanization. The study aimed at providing useful experience for the urbanization.展开更多
