  • 决定系数 - 引用次数:18

    An exponential relation between soil respiration rate and soil volumetric moisture with small determination coefficient (R20-5=0.440, R25-10 =0.521) in growing period. During dormant period, no function could be fit to show relationship between soil respiration rate and soil volumetric moisture.

    植物生长季0~5cm和5~10 cm土层的土壤体积含水率虽与土壤呼吸速率间存在指数关系,但回归方程的决定系数不高(R20-5=0.440, R25-10 =0.521),植物休眠季土壤体积含水率与土壤呼吸速率无明显的回归关系。
