为了提高土地整治项目实施的综合效益,从众多规划方案中选择最优方案成为项目规划设计的关键。论文以甘肃省庆阳市西峰区肖金镇双桐村土地整治项目为例,从不同的角度设计出了4种项目工程建设方案,在此基础上根据建设工程内容和投资水平等资料,构建了带层次分析法(Analytic Hierarchy Process, AHP)约束锥的数据包络分析(Data Envelopment Analysis,DEA)模型,对4个可行方案的土地整治综合效益进行评价。结果显示:方案1~4的最优值依次为1.000 0、0.864 5、0.652 7、0.963 8,方案1为最优,方案4次之。研究表明:AHP-DEA模型将传统DEA方法对输入输出数据的客观分析与决策者的主观偏好结合起来,评价结果客观准确,在土地整治项目规划方案比选中是一种理想的方法。 |

To promote the comprehensive land consolidation results of specific land consolidation project, the key is to design different schemes and select the best one. In this paper, the project of land consolidation for Shuangtong Village in Qingyang city of Gansu Province, China, was chosen as an example. Four schemas were designed for the land consolidation project for different perspectives: schema equally emphasizing on ecology and economy, schema dominated by economic benefits, schema matched with infrastructure and schema guaranteeing people's livelihood. Two indicators, total investment and labor input, were chosen according to the items, the investment level and efficiency measurement of the project. Another five indicators were chosen according to yield to set up indicator system, which are the yield added value per unit area, the static return on investment return, the rate of increased farmland, the increment of annual net income per capita and the increment of vegetation coverage. With the two groups of indicators, a DEA model with AHP constraint cone was created and then the four schemes were compared. The values of the four schemes from No.1 to No.4 were as follows: 1.000 0,0.864 5,0.652 7,0.963 8,suggesting the first scheme (the schema equally emphasizing on ecology and economy) was the best one, followed by the fourth scheme (the schema guaranteeing people's livelihood), then the second scheme(dominated by economic benefits) and finally the third scheme (schema matched with infrastructure). The study showed that the DEA model could combine the traditional objective analysis of input and output data with the subjective preference of decision-maker and adopt the advantages of AHP and DEA could produce more objective and accurate evaluation results than that only by AHP or DEA. The study also demonstrated that both ecological and economic benefits should be considered to promote the result of land consolidation. People's wish to improve livelihood should also be considered when designing land project scheme. The study provided scientific methods for comparing and selecting the design scheme of land consolidation project, put forward suggestion for the main perspective of designing land consolidation plans, and provided preference for reasonable evaluation and conduction of land consolidation. |
