我们试图从不同经营方式的经济效益出发,通过对吉林省梨树县榆树台林场杨树人工林不同经营方式的经济效益剖析,确定梨树县沙地营造杨树人工林的最佳经营途径。梨树县位于吉林省中南部,属于温带半湿润季风大陆性气候。其西部的沈洋、刘家馆、林海、四棵树、胜利等5个乡,地处科尔沁沙地南缘,是全县主要风沙区。这5个乡的土地面积占全县23.8%,人工林面积占全县37.6%,但在沙地上营造的杨树人工林面积却占全县97.6%;是营造杨树速生丰产林的主要基地。
Based on the economic benefits of different management methods, we analyzed the economic benefits of poplar plantations in Yushu Tailin Farm, Lishu County, Jilin Province, and determined the best ways to establish poplar plantations in Lhasa County. Lishu County, located in central and southern Jilin Province, is a temperate semi-humid monsoon continental climate. Its western Shen Yang, Liu Hall, Linhai, four trees, victory and other five townships, is located in the southern margin of Horqin sandy land, the county is the main sand area. The five townships occupy 23.8% of the county’s land area and the plantation area accounts for 37.6% of the county. However, the poplar plantation area in the sand area accounts for 97.6% of the county. It is the main base for planting poplar fast-growing and high-yield forests .
