基于GIS的湖南柑橘种植气候适宜性区划研究

GIS-Based Study on the Climatic Suitability Zoning for Citrus Cultivation in Hunan Province

摘要: 通过梳理国内外有关柑橘气象因子的研究文献，本研究聚焦于最高温度、最低温度及降雨量三项核心气象要素，借助ArcGIS平台的气候要素精细化栅格数学模型，对邵阳地区开展了柑橘种植气候适宜性空间区划研究。结果表明：最适宜种植区主要分布于邵阳市主城区、新邵县全域、隆回县东部、邵东市外围非核心区域及邵阳县大部分地区；适宜种植区集中分布于洞口县、隆回县西部、武冈市–新宁县–邵阳县三县交界地带，以及邵东市中心城区；次适宜种植区主要涵盖绥宁县、武冈市及新宁县全域；不适宜种植区以城步苗族自治县为主体区域。

Abstract: By reviewing domestic and international research literature on citrus meteorological factors, this study focuses on three core meteorological elements: maximum temperature, minimum temperature, and precipitation. Utilizing the ArcGIS platform’s refined grid mathematical model for climate elements, a spatial zoning study on the climatic suitability for citrus cultivation in the Shaoyang region was conducted. Results indicate: The most suitable planting zones are primarily distributed in the main urban area of Shaoyang City, the entire territory of Xinshao County, the eastern part of Longhui County, the peripheral non-core areas of Shaodong City, and most of Shaoyang County; Suitable cultivation zones are concentrated in Dongkou County, western Longhui County, the tri-county junction area of Wugang City-Xinning County-Shaoyang County, and the central urban area of Shaodong City; Less suitable zones primarily encompass Suining County, Wugang City, and the entirety of Xinning County; Unsuitable zones are centered around Chengbu Miao Autonomous County.
