| Abstract: | 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. |
