- 摘要:
- 水土流失是自然因素和人为因素综合作用的结果，其中人为因素是重要因素。海南岛植树造林面积的大幅度增加，使水土流失得到了控制，水土流失面积近年来基本稳定在5.47万hm2。海南岛植树造林的树种较单一，森林林龄较低，森林在保持水土、防风固沙方面的生态效益较低。在今后的水土保持工作中应构建多树种强生态功能的水土保持林，重视和加强科学研究，提高森林的水土保持效益。
- Abstract:
- The soil erosion is the result from the natural factor and artificial factor. The artificial factor is the key factor. In Hainan Islands, increment of afforestation area, making the soil erosion area got control, is 54 700 hm2 in recent years. However, in Hainan Islands, the tree kind used for afforestation is simple, the age of forest is short, and the efficiency of forest keeping water, soil and sand in the ecosystem is lower. It is the key to set up forest to conservate water and soil, to strengthen ecological function of woods and to raise the efficieny of the water and soil conservation based scientific research.
