| 摘 要： | 根据辽宁朝阳近500年的气候考察资料,分析了其十年九旱的成因。结果表明:干旱的发生不仅与大气环流有关,而且与地方的生态环境,尤其与森林植被有直接关系,森林植被的毁坏可增加地方性干旱29.2%。由此提出了建立地方性生态体系,迅速增加森林植被的覆盖度,逐步缓解干旱程度的长期战略思想。同时还提出了近期防御干旱的途径。

| Abstract: | The cause of formation of aridity in Chaoyang region is to be analyzed based on the survey information about climate near to five centuries in Chaoyang,and the results showed that the occurring of aridity is not only related with atmospheric circumfluence but also the environment of this area,especially relate directly with the forest and vegetations.And the demolish of plantation may increase the area aridity about 29.2 %.Hence a strategic thinking of establishing of area ecological system in a long term is bring forward here by which the cover degree of plantation should be increased rapidly to solve the aridity.Meanwhile,the approach to recovery aridity is put forward,too. |
