灰色系统理论是华中工学院邓聚龙教授于1982年创立的。这一理论在农业、气象、林业等行业应用,效果较为理想。目前,灰色系统理论已在我省林业调查设计中试验应用,效果良好。现将应用灰色关联度分析确定主导立地因子的试验情况初报如下。 1 问题的提出辽宁省林业区划、规划经过几年的努力已经完成,对直接影响造林成败的生态区域已经划定。今后对辽西、北在沿河两岸营造杨树速生丰产林的主要研究任务之一,是在众多的立地因子中,确定哪些是影响树木生长的主导因子,
The theory of gray system was founded by Professor Deng Ju-long of Huazhong University of Science and Technology in 1982. This theory in agriculture, meteorology, forestry and other industries, the effect is more satisfactory. At present, the gray system theory has been tested and applied in the forestry investigation and design in our province, with good results. Now the application of gray correlation analysis to determine the dominant site factors in the initial report as follows. 1 PROBLEM PROPOSAL The forestry zoning and planning in Liaoning Province have been completed after several years of hard work and the ecological zones that directly affect the success or failure of afforestation have been delineated. In the future, one of the major research tasks of poplar fast-growing and high-yield forests in the western Liaoning and north of the Yangtze River is to determine which of the many site factors affect the growth of trees.
