【摘要】：以长汀县园地、林地和草地为评价对象,选取地形、气候、土壤、区位和生态环境5方面共11个因子,构建长汀县茶园适宜性评价指标体系。在GIS支持下,运用层次分析法、模糊数学法和综合指数法建立茶园适宜性评价模型,应用动态聚类分析法对评价结果进行分类。结果表明:长汀县适宜种植茶叶的面积为167 288.21 hm~2,占全县园地、林地和草地总面积的61.64%,其中高度适宜区和中度适宜区面积分别为33 674.52 hm~2和87 721.95 hm~2,分别占全县适宜茶叶种植面积的20.13%、52.44%。高度适宜区主要分布在濯田镇、南山镇、宜成乡和涂坊镇,面积共为23 535.89 hm~2,占全县高度适宜总面积的69.89%。利用该结果可为长汀县茶园合理建设和茶叶稳产增收提供科学指导。
[Abstract]:Taking Changting county garden land, woodland and grassland as evaluation objects, 11 factors including topography, climate, soil, location and ecological environment were selected to construct the evaluation index system of tea garden suitability in Changting County. With the support of GIS, AHP was used to evaluate the suitability of tea garden in Changting County. The evaluation model of tea garden suitability was established by fuzzy mathematics method and comprehensive index method, and the evaluation results were classified by dynamic cluster analysis. The results showed that the suitable area for tea cultivation in Changting County was 167,288.21 hmm2, accounting for the whole garden land of the whole county. The total area of woodland and grassland was 61.64, in which the areas of highly suitable area and moderately suitable area were 33 674.52 hm~2 and 87 721.95 hm~2 respectively, accounting for 20.131352.44 of the suitable area for tea cultivation in the whole county, respectively. The highly suitable area was mainly distributed in Zhuotian Town, Nanshan Town, Yicheng Township and Tufang Town. The total area is 23 535.89 hmm2, which accounts for 69.89% of the whole county's highly suitable total area. The results can provide scientific guidance for the rational construction of tea garden in Changting County and the steady increase of tea production and income.
