Climate suitability evaluation for tea planting in Hunan Province
摘要
Abstract
[Purpose]The impact of climate conditions in Hunan Province on tea tree planting were explored to evaluate the suita-bility of various planting regions in Hunan for tea tree planting.[Method]Based on meteorological data from 97 meteorological sta-tions in Hunan Province from 1991 to 2020 and information of 105 tea planting sites,the key climate factors affecting tea cultivation were selected by MaxEnt model to simulate the climate suitability of Hunan for tea planting.Within the GIS platform,climate suita-bility zoning for tea planting in Hunan was carried out,and thresholds for various climate factors were obtained in reference to Max-Ent sensitive characteristic curve.[Result](1)The key factors affecting the climate suitability for tea tree planting in Hunan in-cluded average relative humidity from March to October,annual sunshine hours,spring frost frequency,annual precipitation,and average temperature of the coldest month.(2)According to the climate suitability index M simulated by MaxEnt model,Hunan was graded into 4 areas for tea tree planting:suboptimal area(M<0.20),primarily suitable area(0.20≤M<0.40),suitable area(0.40≤M<0.60),optimal area(M≥0.60).[Conclusion]For tea tree planting in Hunan,the suitable area was the largest and the suboptimal area was the smallest.The simulated climate suitability zoning results were highly consistent with the high-yield pro-duction areas,indicating a good simulation effect by MaxEnt model.关键词
