| ［目的］文章从公平性和效率性2个方面选取6个指标构建了缺水地区微观主体农用水权初始分配指标体系，在该指标体系基础上，提出了投影寻踪混沌粒子群优化模型，研究了在土地流转背景下如何对缺水地区微观主体农用水权进行初始分配的问题。［方法］该文利用了投影寻踪技术对微观主体农用水权初始分配问题进行降维处理，采用混沌优化和粒子群优化算法寻找最优投影方向，并通过算例验证分析证明了该模型的可行性、合理性和有效性，为农用水权初始分配问题提供了相应的方法和思路。［结果］研究认为，土地流转使农业生产向土地规模化、经营主体职业化、分工专业化方向发展，为农用水权在微观主体之间进行初始分配提供了条件；农用初始水权明晰有利于缺水地区优化农业用水结构，节约农业用水，实施农用水权置换，促进农业用水转向第二、三产业，以推动缺水地区产业结构优化升级、社会经济转型发展；在农用水权初始分配过程中各指标重要性水平不能主观评估，应当由不同地区的样本数据驱动，客观地计算决策方案的最优值，公正地确定权重和水权分配比例。［结论］农用水权初始分配应考虑法律制度政策、社会经济、生态环境等多种因素，以构建完善的农用水权初始分配体系。 |

| Abstract: |
| The paper constructed an evaluation index system of initial agricultural water right allocation in water shortage area by selecting six indicators related to fairness and efficiency, and then established the Chaotic particle swarm optimization (CPSO) and projection pursuit (PP) model to research the initial agricultural water right allocation in water shortage area in the background of land circulation. The PP model was adopted to reduce the dimensions of the decision-making problem of initial agricultural water right allocation and the CPSO model was used to search the optimum projection direction. Meanwhile, the feasibility, reasonableness and effectiveness of the model were verified by an example calculation and comparative analysis. The empirical analysis results showed that land circulation made agricultural production towards land scale, professionalism of the main body, agricultural specialization, and gradual centralization of agriculture; What′s more, the clarity of agricultural water right could optimize agricultural water structure, agricultural water conservation, agricultural water rights exchange, and promote agricultural water rights transform from agriculture to secondary industry and tertiary industry. It also could improve the optimization and upgrading of industrial structure, social development and economic transformation. The optimum value of various schemes should be calculated objectively and the weight of each index should be determined fairly, based on the sample data of various areas. Additionally, a complete initial agricultural water right allocation system should take into account the factors, such as laws, systems, policies, socio-economic, ecological and environmental factors. |
