Euphrates poplar(Populus euphratica Oliv.) is the only tree in desert zones in China. It is playing an important role in safeguarding the balance of ecosystem, providing timber, fire wood and fodder.As the euphrates poplar forest decreased greatly, the ecological conditions in many zones has worsened.That is why conserving, recovering and developing the forest is an urgent matter.Correct definiting the soil conditions is the foundation for carrying out this task.This paper indicates that euphrates poplar resists arid and waterlogging but neither a xerophyte nor a marsh plant; salt-toleranted but not a halophyte; wind and sand combated but not a sand plant.The recovery and development of euphrates poplar forest must be according to the conditions of soil moisture and salt content, and then take appropriate measures, such as closed forest, regenerated forest under sprout and pollarding, forest from farmlands, irrigated forest by flood and planting seedlings.It may be the major species for sheltbelt establishment in irrigated salt-alkali farmlands in arid zones.

胡杨是我国荒漠地区唯一的乔木树种,在维护干旱地区的生态平衡、提供用材、燃料和饲料等方面,都具有重要作用。由于胡杨林大面积减少,不少地区生态条件恶化,维护、恢复和发展胡杨林是当务之急,而正确评价其土壤条件是进行这一工作的基础。研究表明,胡杨抗旱但非旱生,耐涝但非沼生,耐盐但非盐生,抗风沙但非沙生(树种)。胡杨的恢复和发展要围绕土壤条件特别是水分和盐分条件因地制宜地采取相应的措施,如封滩育林、挖桩更新、断根萌蘖、头木作业、退耕还林、引洪灌溉和人工造林等。胡杨抗盐耐涝还可作为干旱地区盐碱地护田林的主要造林树种。

The microclimatic efficiency of wide water area and regenerated forest vegetation in Qiandao Lake's region was obvious. This article discussed the influences of microclimate, heat and water factors on the tree growth. The results proved that in this region the rainfall and heat resource all year were favourable to prolong the growing seasons, to decrease the freezing and dry hazards, to increase the growth rate, and to make up a good microclimate for introduction of many exotic tree species.

浙江省淳安县千岛湖由于有广阔的水面和经封山育林30年恢复的森林植被,形成的小气候效应十分明显。本文探讨了小气候条件:热量和水分因子,小气候效应和林木生长发育的关系。说明该地区的降水量充沛,热量资源丰富,具有冬暖夏凉的小气候特征,从而延长了林木的生长期,减轻了冻害和旱害,促进了林木的生长,为一些树种的北移创造了小气候条件。
