Abstract: The drought resistance, heat tolerance of 26 main landscaping tree species planted in Panzhihua City were assessed by measuring 9 physiological indexes including water content, saturated water content, specific leaf area, juicy degree, saturation deficit, death saturation difference, death saturation deficit, relative drought index, and heat tolerance. Combined with native tree species inventory, the tree species suitable to be grown for urban forest building in Panzhihua City were recommended.
