FAMILY MODELS USED IN OPTIMAL ALLOCATION OF REGIONAL LAND USE
1999, 18 (1):
The optimal allocation of land use not only include the macroscopic optimization of the structural pattern of quantity and space, but also include the reasonable matching of productive factors in microcosmic scale. Thus, it is a multi objective and hierarchic sustainability process of fitted measure. Taking Yueqin city as an example, the new method to study the optimal allocation of land use in county region using family model is put forward in this paper. The family model are composed of three patterns, namely, spatial zone, structural optimization and microcosmic design model according to the internal relation of optimal allocation objectives of land use, which can give play to itself single action and synthetic advantage to coordinate relation between quantity and space, macroscopic and microcosmic in the light of their identity and complementary in the allocation and measure. Therefore it has wide application prospect. Although there are different visual angles among three models, they own common center to seek for the topgallant structural effects of land use. Their combinative way is to build harmonious mechanism between the suitable expansion of non agricultural constructive land and efficient preservation of cultivated land and microcosmic stimulant mechanism of intensive use of various lands. Its essence is that the optimal combination of two powers, expanding out of constructive land in town and the regulative constraint of basic farm, will be put into together. The optimal allocation of land use is a unity between land productivity organization and land production relation coordination. Therefore, its tasks are not only to promote regional industrial structure upgrade and optimal layout by carrying out the plan of optimal allocation of land use, but also to actuate the reasonable matching of microcosmic productive factors in land use depends on the progress of science and technique and the perfection of market mechanism.
