摘要
土地利用优化配置，既包括宏观数量与空间结构格局的优化，也包括微观尺度生产要素的合理比配，是一个多目标、多层次的持续拟合与决策过程。本文结合乐清市实证研究，提出了运用系列模型研究县域土地利用优化配置的新方法。系列模型由空间分区模型、结构优化模型和微观设计模型，按照土地资源优化配置目标的内在联系性组合而成。系列模型既能够发挥单个模型的作用，也能充分利用它们在土地利用优化配置与决策中所具有的同一性与互补性，在科学协调土地利用配置数量与空间、宏观与微观之间的关系中更好地发挥其综合优势，因而具有广阔的应用前景。
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.
