Climate regionalization for walnut plant in Shaanxi province based on GIS
摘要
Abstract
Based on the meteorological data of 96 weather stations from 1981 to 2010 and geographical information in Shaanxi province ,GIS technology was employed for climatic divisions of walnut to provide scientific basis for sustain-able development .Through the analyses of climatic suitability and characteristics in Shaanxi ,five indexes including an-nual mean temperature ,annual mean precipitation ,annual mean sunshine hours ,extremely minimum temperature ,and the day numbers of daily maximum temperature ≥38℃ ,were selected as the climatic regionalization criteria .Subse-quently ,small grid reckon model was established to calculate the spatial distributions of each regionalization index values using GIS technology .Comprehensive evaluation method was further used to assess the distribution graph of the climati-cally suitable planting areas for walnut . The results indicated that the suitable regions were distributed in northern Shaanxi from the area along Ansai ,Zichang ,Qingjian ,and Wubu to the area along Hanjiang river;and in southern Shaanxi ,these regions included the Loess Hilly and Gully Region of Northern Shaanxi ,the northern bank of Weihe river , Central Shaanxi Plain ,and the valley and shallow mountain areas of Qinling ,excluding the remote mountain areas of Qinling ,Longshan ,and Huanglong .The suitable region of the northern Weibei Plateau and the high altitude areas of North Slope of Qinling Mountains should select anti-frost walnut varieties planting in sheltered sunny and semi-sunny slope region;And that of Bashan Mountains may choose walnut varieties with good moisture and strong disease resistance .关键词
