一、林木种子质量评价的复杂性与模糊性林木种子质量(播种品质)是一个极复杂的动态变化系统,与复杂性紧紧相伴的便是模糊性。而以往种子质量评价参数的赋权其复杂性与模糊性又集中体现人的智力活动参与其中。在参数赋权上至今仍基本沿袭人为主观判断权重的工作方式。然而,人的主观判断意识并非简单的二值逻辑,而是一种不明确的连续逻辑。同时,在判断某参数是否“重要”各人的阈值 First, the complexity and fuzziness of tree seed quality evaluation Forest seed quality (sowing quality) is a very complex system of dynamic changes, closely linked with complexity is fuzziness. In the past, the complexity and fuzziness of weighting parameters of seed evaluation also reflected the participation of human intelligence activities. In the parameter empowerment is still basically follow the man to determine the weight of subjective work. However, the subjective sense of consciousness is not a simple binary logic, but an ambiguous continuous logic. At the same time, in determining whether a parameter “important” each threshold
