朝阳地区是“七山、一水、二分田”的山区,山上现有林是大面积油松、刺槐,目前还没有促其速生丰产的办法,现有的荒山宜林地,除了一些局部缓坡、丘陵厚层土地块,可试行培育刺槐速生林外,条件都很差,只能做一般的绿化用地。发展速生丰产林,也只能从“一水、二分田”上来考虑。通过大搞“四旁”绿化;实行农田林网化;营造河流护岸、固沟速生林,才是我区的三大木材生产渠道和重要途径。因此,在狠抓“四旁”绿化和农田林网化同时,必须充分认识,这一份“水”的重要,其潜力很大,要充分利用,结合护岸、固沟,建设大面积的速生用材林基地,是完全可能的。与大面积荒山绿化相配合,既可起到防洪保田作用,又可兼得速生用材。
The existing forest in the mountains is a large area of Pinus tabulaeformis and Robinia pseudoacacia. At present, there is no way to promote its fast-growing and high-yielding. The existing barren hills are suitable for forest land except some gentle slope, Hilly thick layer of land, perennial Robinia pseudoacacia fast growing forest, the conditions are poor, can only do the general green land. Development of fast-growing high-yield forest, only from the “one water, two fields” to consider. Through the vigorous “four sides” afforestation; the implementation of farmland network; to create river bank protection, fast furrows, is my area’s three major timber production channels and an important way. Therefore, while paying close attention to the greening of the “four sides” and the network of farmland forests, we must fully understand that the importance of this “water” is great and that we should make full use of it. Base, it is entirely possible. With a large area of afforestation with barren hills, can play the role of flood control Po Tin, but also have fast-growing timber.
