Abstract:  Tricholoma matsutak is a precious?edible and medicinalwild fungus withrich nutrition. Xiangcheng county is one of the main producing areas of T. matsutake, but its spatial distribution was not very clear for the vast area, sparse population, complex topography and most of the previous research methods were field surveys of typical areas. Based on the previous research results and field investigation, this paper summarized the suitability regionalization indices of the growth of T. matsutake in Xiangcheng county, such as altitude, temperature, precipitation, vegetation and terrain slope. Then, the climate ecological suitability and potential distribution of T. matsutake in this county were analyzed by using the spatial analysis method of Geographical Information System(GIS).The results showed that:(1)T. matsutake grows in 12 villages and towns,but its distribution areasare band-shaped and branch-like alongthe mountain range direction under the influence of the terrain and climate. The main producing areas are Baiyi, Reda, Dingbo, Zhengdou and Shagong in thecounty. (2)The altitude of the suitable area is from 3000 to 3900 meters above sea level, the average temperature is between 10.0and 14.5°C, and the precipitation ranges is 500-800mmfrom April to October. T.matsutake likes to grow in alpine oak forest, pine forest or mixed forest with medium and high coverage, and the slope of these forests should be 25°-35°. In the sub suitable area, the altitude is 2800-3000m or 3900-4200m, the average temperature is 7.5-10.0℃ or 14.5-16.0℃, the precipitation is 400-500mm or more than 800mm from April to October, and the vegetation is alpine oak forest, pine forest or mixed forest with low coverage, the slope of these forests should be 15°-25° or 35°-45°. Meadows or no vegetation areas are the unsuitable areas for T.matsutake.The suitable area accounts for 19% of the total area of the county, the sub suitable area accounts for 16% of the total area of the county, and the unsuitable area accounts for 65% of the total area of the county.(3)The most suitable weather condition for mushroom growing is sunny day and rainy night from late July to mid September. During this period, the average temperature is about 16℃, the total precipitation is about 260mm, the relative humidity is more than 70%, and the total sunshine hours are 228-255h.(4)The verificationresults showed that 92% of the villages and towns were consistent or basically consistent with the actual situation, which showed that the indicators of the zoning were reasonable. The conclusion of this study is of great significance to the picking, trade and resource protection of T. matsutake.
