前言平潭县自从引种抗风固沙木麻黄树种后,大部分沙荒已经绿化,风速显著下降,流沙全面固定,防护林初步形成,长期失调的生态因子开始向平衡方向发展,从而给社会经济各个方面带来显著的效益。然而,在木麻黄基干林的前缘,还存在着岸涂广阔,生境恶劣的沃岸流动沙荒,其潮涌上岸的海沙,在大风吹动下,猛烈地向基干林进逼,随着流沙量的增加,于基干林前缘,聚沙成丘,淹埋林木,有的甚至突口而入,埋没耕地,长此下去,势必引起基干林全面被毁,风沙灾害再起。
INTRODUCTION Since the introduction of wind-resistant sand-hardwood ephedra species in Pingtan County, most of the sand-wasteland has been afforestated, the wind speed has decreased significantly, the quicksand has been completely fixed, and the shelterbelts have been initially formed. The ecological factors of long-term imbalance have started to develop in a balanced direction, To significant benefits. However, on the front of the Casuarina Dried Forest, there is still a vast sand-wadded shrub land with a large expanse of land and a harsh habitat. Increase in the forefront of the trunk forest, gather into the mound, submerged trees, and some even into the hole, buried land, the long run, is bound to cause the basic dry forest was completely destroyed, the sandstorm disaster resurgence.
