漫衰减系数K(z)是湖泊光学研究中的重要光学参数,而其中下行漫衰减系数K_d(z)目前的计算方法主要是经验算法,而这些方法对于理解K_d(z)以及影响Kd(z)计算不确定性的分析是远远不够的,本文通过求解辐射传输方程得到K(z)的解析模型,分析固有光学属性(b_b(z))/(a_(z))以及表观光学属性(1)/(u_d(z))和(1)/(u_u(z))对计算K(z)时误差引入的敏感度,根据其敏感度为0的分界点,推演出K_d(z)在(b_b(z))/(a(z))<1和(b_b(z))/(a(z))1条件下的综合分段模型,预测值与Hydrolight模拟值方差为1.0023,标准差为1.0011.

Diffuse attenuation coefficient K(z) is an important optical parameter in the research of lake optical property, the current calculation methods of downwelling diffuse attenuation coefficient K_d(z) is mainly experience algorithm, and all of these methods for understanding K_d(z) and the uncertainty effects of the K_d(z) analysis are far from enough.By resolving the radiation transfer equation, we got the analytical model of K_d(z), by analysing of the sensitivity degree of the inherent optical properties (b_b(z))/(a(z)) and the apparent optical properties (1)/(u_d(z)),(1)/(u_u(z)) to the introducing error when calculate Kd(z), we deduced the Kd(z)'s Sub-integrated model under the condition of (b_b(z))/(a(z))<1 and (b_b(z))/(a(z))1 according to the zero sensitivity boundaries points, the variance and standard deviation between the Hydrolight simulation and predictive value of model is 1.0023 and 1.0011 respectively.
