一、以自然地理特征为依据,因地制宜地确定森林经营方针辽宁东部山区山地走向与海岸线平行,受季风影响,加上地形的阻滞和抬升作用,致使东部山区的降水量超过东北各地,达到亚热带季风区降雨的水平.详见表1. 上述独特的水热配合情况,必然引起其他一系列特异情况的产生,其特点主要有: First, based on the natural and geographical features, according to local conditions to determine the forest management guidelines Mountain in eastern Liaoning mountainous and coastal parallel, affected by the monsoon, combined with topography of the block and uplift, resulting in precipitation in the eastern mountainous areas beyond the Northeast, reach the subtropical Monsoon rainfall levels as shown in Table 1. The unique combination of water and heat, will inevitably lead to a series of other special circumstances, its characteristics are:
