摘要
【目的】为四川省李子产业合理规划布局和优化产业结构提供参考。【方法】利用四川省145个气象站点2009—2018年的气象数据,结合全省李子主产区的气候条件,以年平均温度、≥10℃有效积温、冬季需冷量、2月平均气温、降水量、日照时数以及海拔作为李子气候适宜性区划的评价指标。基于地理信息系统(GIS)技术平台和空间插值分析四川省各区域的气象要素值,将适宜性划分为最适宜、适宜、次适宜和不适宜4个等级。【结果】四川省李子栽培的最适宜区包括四川盆地中部、东部和川西南山地部分地区;适宜区包括四川盆地东南部和盆周西部山地;次适宜区包括川西北高原与四川盆地的过渡地带;不适宜区主要分布在川西北高原。【结论】区划结果与四川李子种植现状吻合度较高,为四川省李子栽培的合理布局提供了科学依据。
【Objective】The objective of this research is to offer a scholarly resource that focuses on the strategic planning and optimization of the industrial structure and layout within the plum industry in Sich⁃uan Province.【Method】By utilizing meteorological data obtained from 145 meteorological stations in Si⁃chuan Province from 2009 to 2018,and considering the climatic conditions prevalent in the primary plum production areas of the province,we have arrived at a comprehensive set of evaluation indicators for regionalizing of plum cultivation based on climatic suitability.These indicators encompass the average an⁃nual temperature,cumulative temperature exceeding 10℃,winter cold requirements,average tempera⁃ture in February,precipitation levels,sunshine hours,and altitude.Through the utilization of Geo⁃graphic Information System(GIS)technology and spatial interpolation,we have analyzed the values of these meteorological elements in each distinct region of Sichuan Province.The analysis categorizes the suitability of each region into four grades:most suitable,suitable,sub-suitable,and unsuitable.【Re⁃sult】The most suitable locations for plum cultivation in Sichuan Province are primarily concentrated in the central and eastern regions of the basin,as well as certain mountainous areas in the southwestern part of Sichuan.The suitable areas extend to the southeastern portion of the Sichuan Basin and the surround⁃ing western mountainous regions.The sub-suitable areas are situated in the transitional zone between the northwest Sichuan Plateau and the Sichuan Basin. On the other hand, the unsuitable areas are predomi⁃ nantly located in the northwest Sichuan Plateau. 【Conclusion】 The results are consistent with the cur⁃ rent status of plum cultivation in Sichuan, offering a scientific foundation for the strategic arrangement of plum cultivation in Sichuan Province.
