摘 要:针对晋江流域的生态地质问题,应用Getis-Ord Gi*统计模型、Calinski-Harabasz指数评价聚类模型等评价方法,从脆弱性分级、主控因素、聚集特征三方面开展脆弱性评价,建立晋江流域生态环境脆弱性评价模型。整体来看,晋江流域西溪比东溪脆弱,上游比下游脆弱;晋江流域东南部城市聚集区脆弱性的主控因素为建筑用地、初级生产力与土壤有机质,中西部茶叶种植区的主控因素为茶叶的过度种植;脆弱性高值聚集区域在安溪县感德镇以及永春县湖洋镇一带。在上述分析的基础上,对晋江流域茶园种植分布现状合理性进行评估,给出具体的茶园空间优化建议。In view of the increasingly prominent ecological geological problems in Jinjiang River Basin,it is urgent to strengthen the protection of ecological environment and carry out ecological environment vulnerability assessment,which can provide decision-making basis for ecological environment protection.The vulnerability assessment model of ecological environment system in Jinjiang River Basin is established.Using Getis-Ord GI*statistical model,Calinski-Harabasz index evaluation clustering model and other evaluation methods,vulnerability assessment is carried out from three aspects:vulnerability classification,main control factors and aggregation characteristics.The results show that in terms of vulnerability,Xixi is more vulnerable than Dongxi,and the upstream is more vulnerable than the downstream.In terms of main controlling factors,the main controlling factors of vulnerability in the southeast plain of Jinjiang River Basin are construction land,primary productivity and soil organic matter.The main controlling factor of vulnerability in Central and Western China is tea planting.In terms of aggregation characteristics,high vulnerability aggregation areas are Gande town of Anxi County and Huyang Town of Yongchun County.Based on the above analysis,the rationality of the current situation of tea plantation distribution in Jinjiang River Basin is evaluated,and specific suggestions for tea plantation spatial optimization are given.
