塞罕坝地处河北省的最北部,位于内蒙古高原南缘和坝上山地。林区气候寒冷,冬长,春秋短,夏季不明显,属寒温带大陆性季风气候。塞罕坝特殊的地理位置决定了其对阻滞浑善达克沙地南移,涵养滦河和辽河水源,阻挡风沙对京津的侵袭有着极其重要的影响。因此,在保护好山区现有植被的同时,积极开展荒山造林扩大植被面积,对维护区域生态平衡,有重要作用。本文结合塞罕坝地区实际情况,浅谈提高当地宜林荒山造林成活率技术措施。
Saihanba is located in the northernmost part of Hebei Province, located in the southern edge of Inner Mongolia Plateau and Bashang mountains. Forest climate is cold, long winter, short spring and summer, summer is not obvious, is a cold temperate continental monsoon climate. The special geographical location of Saihanba determines its extremely important influence on blocking the southward movement of Hunshandake Sandyards, conserving Luanhe River and Liaohe River water source, and stopping the sandstorm from affecting Beijing-Tianjin. Therefore, while protecting the existing vegetation in mountainous areas, it is also important for afforestation and afforestation to expand the area of vegetation in order to maintain regional ecological balance. Based on the actual situation in Saihanba region, this paper discusses the technical measures to improve the survival rate of afforestation on the local afforested forests.
