Optimal Arrangement of Flue-cured Tobacco Plantation in Changting by GIS Technology
-
摘要: 以南方水土流失典型区长汀县为研究区域, 基于“适地-区位-集约”的用地优化布局理念, 借助GIS与数学模型集成技术, 在烤烟用地适宜性评价基础上, 开展长汀县烤烟用地优化布局研究。结果显示, 长汀县适宜种植烤烟的耕地占全县耕地总面积的88.08%, 以高度和中度适宜占优势, 合计占耕地总面积的79.74%;全县烤烟用地优化布局类型区以优先种植区和次优先种植区占绝对优势, 合计占全县烤烟优化布局用地区总面积的92.82%;大同、河田、童坊、新桥和濯田等乡镇可作为长汀县烤烟产业的重点发展区, 策武、古城、馆前和涂坊等乡镇可作为后备发展区。Abstract: Taking an instance of soil and water erosion for case study on the optimization layout of plantation land, the layout of flue-cured tobacco plantation in Changting was optimized based on the principle in“suitability, localization and intensives”with integration of GIS and mathematical modeling.The results showed that, account of total cropland in Changting, the area suited for flue-cured tobacco plantation was 80.08%, and 79.74% of which was high or moderate suitability.Among total flue-cured tobacco plantation land, the optimal localization in suitability showed that the first and secondary suitable planting area was for 92.82% in total optimized arrangement.The towns including Datong, Hetian, Tongfang, Xinqiao and Zhoutian could be planning as key developing area, and those including Cewu, Gucheng, Guanqian and Tufang could be planning as reserve area for flue-cured tobacco industry in Changting.
