| Abstract: |
| 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 implementation, 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 optimal 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 accounted 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 directly serviced to select the local wine grape bases and promoting the regional development. |
