摘要
本文利用模糊综合评判法对秋季飞播造林时间进行评价,分别以影响飞播成效的降雨量、降雨天数、气温以及幼苗生长期等因素作为评判因子,构造评判因子与飞播期优劣的关系矩阵,结合实例利用模糊运算得出秋季播种的最佳时间。
The factors such as the amount of rainfall, day numbers of rainfall, temperature and seedling growth were collected in fuzzy comprehensive evaluation for determining the time of automn aerial seeding. Relationship matrix for judgment was established and the optimum time for autumn aerial seeding was calculated.
