利用云模型评价开发区的土地集约利用状况

针对当前开发区土地集约评价中权重确定方法受主观性影响较大的问题,该文提出基于云模型的权重确定方法。将云模型引入开发区土地集约利用评价,并以桂林国家级高新技术产业开发区为例,进行实证研究。研究结果表明桂林高新区土地利用集约度综合分值为0.889,用地供需基本平衡;从土地利用状况而言,其土地利用强度较高、工业用地水平较强;就用地效益而言,工业用地产出强度较好,高新技术产业用地产出强度较高;从管理绩效来看,截止评价时点,区内无闲置土地,监管成效显著。基于云模型确定权重值的方法具备结果更加客观,算法容易实现的优点,有助于促进土地集约利用的科学评价,为桂林高新区土地集约利用政策依据。

Evaluating intensive land use situation of development zone based on cloud models

Due to the problem that current methods obtaining the weight values in intensive land use evaluation is influenced much by subjectivity of experts, cloud models to determine weight values were introduced in this study. Taking Guilin Advanced Technology Industry Development Zone as an example, cloud models was applied in intensive land use evaluation of development zone. Results showed that the comprehensive intensive land use value of Guilin Advanced Technology Industry Development Zone was 0.889, which achieved a sound balance between the supply and demand of land use. The state of land use reached a relatively high level of land use intensity as well as industrial land coverage. Based on land use efficiency, the output intensity of industrial land and high-tech land were both relatively high. In terms of management performance, there was no idle land, which suggested relatively perfect outcome of management. In the end, this paper summarized the advantages of using cloud models by presenting a more objective outcome and more easy-to-achieve algorithm. The application of Cloud Models is conducive to intensive land use evaluation in a more scientific way, so that it will benefit the policy-making processes of Guilin Advanced Technology Industry Development Zone.
