村级土地利用情景决策系统及其应用

Village-level land-use scenario decision-making system and application

本研究试图构建一个村级土地利用情景决策系统,使该系统采用一种交互方式来探索村级土地利用配置问题。以重庆市渝北区龙兴镇为研究对象,运用3种多目标线性规划方法[目标规划法、逐步宽容约束法和Lu等的方法(文献[9]方法)]进行土地资源优化配置并评价其结果。结果表明:建立的村级土地利用情景决策系统可用各种方式将多个目标合并成一个单一目标,从而为给定问题提供不同的解决方案;对不同方法的资源优化配置结果进行了检查,以协调和权衡不同目标优先级情形下的冲突,使最终的决策更具有明确的指向性。只要研究区满足以下几个标准,村级土地利用情景决策系统就可以进行调整,以适用于新的研究背景:(1)研究区接近城市;(2)研究区有较为明显的旅游特征或潜质;(3)研究区是以农业生产为主的区域;(4)研究区有较多样的农业活动。村级土地利用情景决策系统是基于可用的信息和精确的方法,所以不仅使规划更加"透明",还整合协调了各种利益冲突。

An interactive approach,based on village land-use allocation issues,was used to develop a village-level land-use scenario decision-making system.The system was backed up with three multi-goal linear programming methods [goal linear programming method,gradual easy constraint method and Lu＇s method（reference 9）] to complete with optimum allocation of land resources.The effects were tested for Longxing Town in Yubei District,Chongqing City.The results showed the established village-level land-use scenario decision-making system combined multiple objectives into a comprehensive super-objective,and provided different approaches for the given problems.The optimum allocation results of land resources were analyzed to adjust and balance conflicts among objectives with different priority ranks.This in turn strengthened the final decisions due to a fuller understanding of the implications.The village-level land-use scenario decision-making system might be adjusted to be applied on the other scenarios,provided that the studied areas met the several criteria.The criteria included：（1） the studied areas was close to an urban;（2） it was attractive or of potential value for tourism;（3） agriculture was the main land use in the area;and（4） agricultural activity in the area was diversified.Village-level land-use scenario decision-making system based on available information and appropriate approach not only made the planning more transparent,but also integrated and coordinated conflicting among different interests.
