摘要
利用旺苍县50个地面气象站的逐日观测资料,结合旺苍县核桃种植气候适宜性需求,选取年降水量、年平均气温、年日照时数和年≥10℃积温作为气候适宜性区划指标,建立气候因子空间模型,运用GIS技术开展旺苍县核桃种植气候适宜性区划研究。结果表明:旺苍县核桃种植气候适宜性可划分为3类,即最适宜区、适宜区和不适宜区;最适宜区主要分布在旺苍县北部低海拔的高山河谷区,气象条件完全满足核桃种植所需,最适宜核桃种植;适宜区主要分布在旺苍县海拔较高区域,此区域水分条件与日照适宜核桃生长,但热量条件不适宜核桃种植;不适宜区主要集中在旺苍县中部一线及北部高海拔地区,这些区域水分条件和日照同样适宜核桃生长,但热量条件完全不利于核桃种植。
Using the observation data of 50 observation stations in Wangcang County,the annual precipitation,annual average temperature,annual sunshine hours and annual accumulated temperature of≥10℃were selected as the zoning indicators based on the climatic suitability requirements of walnuts in Wangcang County.A regression model between each index and topography was established,too.Using GIS technology,the climatic regionalization of walnut planting in Wangcang County can be divided into 3 types such as the most suitable area,suitable area and unsuitable area.The most suitable area is mainly distributed in the mountainous valley area with low altitude in the north of Wangcang County,and the meteorological conditions fully meet the needs of walmut planting.The suitable area is mainly distributed in the high altitude area of Wangcang County,where the water condition and sunshine are suitable for walnut growth,but the heat condition is not suitable for walnut cultivation.Unsuitable areas are mainly concentrated in the central line of Wangcang County and the northern high-altitude areas,where the water conditions and sunshine are also suitable for walnut growth,but heat conditions are completely not conducive to walnut planting.
