在里下河滩地开发中，形成了不同的人工立地类型，本文通过对I—69杨在不同立地类型条件下，个体结构、树冠结构及生长量的研究比较，总结认为采用筑垛开发滩地的整地措施是培育杨树速生丰产林的关键。研究结果为里下河地区大面积开发滩地资源提供了依据。
In the development of the river beach, different types of artificial landform have been formed. Based on the comparison and research of I-69 Yang under different site types, individual structure, canopy structure and growth, this paper concludes that the use of stacking for the development of beach land Soil preparation measures is the key to cultivating fast-growing poplar forest. The results provide the basis for large area development of beach resources in Lixiahe area.
