基于K-Means聚类算法的凤堰灌区人水和谐特征研究

Characterization of Human-Water Harmony in Fengyan Irrigation District Based on K-Means Clustering Algorithm

为了深入研究凤堰灌区人居景观特征,首先提出了“田地-古村落-水资源”三大要因,运用皮尔逊相关系数计算出水资源决定了灌溉田地的面积与位置,同时一起对村民人口的分布与发展产生影响,即“水资源、田地、古村落”三者之间存在高度的耦合性和关联性,采用K-Means聚类算法对凤堰灌区人水和谐特征与现存状况进行了研究分析,得出了Ⅰ类人均拥水量为8.52m^(3)/人;Ⅱ类人均拥水量为2.47m^(3)/人;Ⅲ类人均拥水量为0.87m^(3)/人,并为三类聚落发展提出不同的建议,充分发挥灌区的原生态优势,为日后营造一个绿水青山、人水和谐的景象,为同类灌区发展研究提供借鉴。

In order to deeply study the characteristics of human landscape in Fengyan Irrigation District,this paper firstly puts forward the three major factors of"field-ancient village-water resource",and uses Pearson's correlation coefficient to calculate that the water resource determines the area and location of irrigated fields,and at the same time influences the distribution and development of the village population,i.e.There is a high degree of coupling and correlation among"water resource,field,and ancient village".There is a high degree of coupling and correlation among water resources,fields and ancient villages.Using K-Means clustering algorithm,we have studied and analyzed the characteristics of human-water harmony and the existing situation in Fengyan Irrigation District,and found that the average per capita water consumption of Class I is 8.52m^(3)/person.The average per capita water consumption of Class II is 2.47m^(3)/person;and the average per capita water consumption of Class III is 0.87m^(3)/person,and provided a good solution for the development of three types of settlements.and put forward different suggestions for the development of the three types of settlements,giving full play to the original ecological advantages of the irrigation area,creating a green water and mountains,human and water harmony for the future,and providing reference for the study of the development of similar irrigation areas.
