基于GIS的宁夏酿酒葡萄优质生态区区划与应用

摘要

At present,the ecological regionalization of wine grape focused on climatic regionalization at home and abroad .In this paper,based on the previous research works,with the principle of“step by step,stratified implementa-tion,selected among outstandings”,comprehensively considered the climate and environmental resources,put forward the ecological regionalization indexes,and using GIS technology,completed the quality ecological regionalization of wine grapes in Ningxia .The results showed that:The most of the middle and north region of Ningxia can be planted wine grapes,this areas accounted about 1/3 of the total land areas of Ningxia .In the cultivable regions of wine grape,the op-timal climatic areas accounted for 32%,which major distributed in the northern irrigation districts,particularly in most areas of the east side of Helan Mountain .In the optimal suitable climatic regions,the ecological optimal regiuon account-ed for 1 .8% which distributed in west of Yinchuan City about 30 km away,the east side of Helan Mountain,Gezi Mountain in Qingtongxia City and parts mountain lands in northern of Baima and Yuding Townships in Zhongning County . This research results can be greatly improved the fine degree of regionalization of wine grape in Ningxia,and can be di-rectly serviced to select the local wine grape bases and promoting the regional development .%目前国内外酿酒葡萄生态区划多侧重于气候区划，本研究在前人研究的基础上，综合考虑气候和环境资源，本着循序渐进、分层推进、优中选优的区划原则，提出酿酒葡萄优质生态区的区划指标，运用GIS技术，完成宁夏酿酒葡萄优质生态区区划。结果表明：宁夏中北部大部地区可以种植酿酒葡萄，约占宁夏国土总面积的1/3；在可种植区域内，气候最适宜区面积占32％，主要集中在北部灌区特别是贺兰山东麓大部地区；在气候最适宜区内，生态特优区占1．8％，分布在距银川市西约30公里的贺兰山东麓，青铜峡鸽子山和中宁白马、余丁乡北部部分山地。研究成果可大大提高宁夏酿酒葡萄区划结果的精细化程度，直接服务当地酿酒葡萄基地选择和区域化发展。
