柏木与枫香三种不同比例的混交林,经过二十年的观察和1985年的实测调查与分析,柏木3行与枫香1行按倾斜度方向进行带、行混交,形成比较稳定的林分群体结构;柏木2行与枫香1行混交,虽然抑制了其他灌木,枫香生长良好,但柏木后期受压;两者单行混交,8年之前枫香树高生长很快,枫香同种内出现竞争,而10年之后柏木生长逐渐赶上枫香,目前柏木长势良好,枫香受到侧方遮荫,长势较差。因此,第一种混交比例可以在千岛湖森林公园建设中进行中试。
Cedar and sweet gum three different proportions of mixed forest, after two decades of observation and 1985 measured survey and analysis, cedar 3 and sweetgum line 1 according to the tilt direction of the band, mixed row to form a relatively stable forest Sub-group structure; Cedar 2 and Liquidambar mixed 1, although the inhibition of other shrubs, sweetgum grow well, but the cedar compression late; both mixed singles, eight years ago, sweetgum tree height grows quickly, Liquidambar Competition within the species, and 10 years after the gradual growth of cypress wood with sweet maple, the current good growth of cypress wood, sweetgum side shade, growth is poor. Therefore, the first mixed rate can be piloted in the construction of Qiandaohu Forest Park.
