A balance of urban datum land prices is achieved to harmonize regional land prices and make the prices truly reflect different economic development levels and land prices among cities. The current piecewise linear interpolation balance method widely used has two drawbacks that always lead to an unsatisfactory balance among some cities. When the excess of land price in the central city to the surrounding zone reaches a certain degree, land price in the circumjacent city is not only consistent with the local land grade and land use level, but also influenced by the diffusion of land price in the central city. Thus, a new balanced scheme of datum land prices based on the city gravitation model and stochastic diffusion equation is brought forward. Finally, the new method is examined in the practice of datum land price balance in Hubei Province, China. 相似文献

基于目标规划与模拟退火算法的土地利用分区优化方法 总被引:1,自引:0,他引:1
以兰州市榆中县为实验区,选取分区适宜性、规划协调性和空间紧凑性作为分区目标,基于目标规划和模拟退火算法对实验区进行土地利用分区优化。结果表明,不同情景下的分区方案能很好地满足决策者设定的目标偏好值;从空间特征分析的结果看,本分区方案较原有分区方案对各个分区目标进行了优化,更好地满足了农业生产、经济发展以及生态保护的要求。 相似文献
