克拜地区约括:克山、克东、纳河、依安、拜泉、明水、海伦、青岗、望奎、兰西、绥化及嫩江、德都、庆安、绥棱等部分地区。这个地区属于小兴安岭西南麓支脉,地形地势是起伏的丘陵漫川漫岗。总土地面积约六千万亩,森林用地面积二百五十五万亩,森林复被率只占百分之四点二五。缺林少树,植被少,侵蚀沟多,水土流失严重逐年侵蚀农田土地,影响农业发展,造成单产不高,总产不稳。为了加速农业生产的发展,确保高产稳产丰收,必须加强领导,积极组织人力物力,做好水土保持工作。为此,我们于八一年六月二十八日至七月二十一日,对早已开展水土保持工作,有代表性的克山、拜泉两县进行了调查。一、水土流失对农业生产的危害及治理后的效果克、拜地区的水土流失,在文革前经过一段时间的治理,取得了明显的效果。但是,由于文化大革命,水土保持机构解散,无人过问,缺乏科学管理,以致滥伐林木,毁林开荒、毁草种地,破坏植物群落。使自然植物生
The areas of Kibai include Keshan, Kedong, Nahe, Yi’an, Baiquan, Mingshui, Helen, Qinggang, Wangkui, Lanxi, Suihua and Nenjiang, Deu, Qing’an and Suiling. . This area belongs to the small limbs southwestern foothills, the topography is undulating hills Mangchuan Man Kong. The total land area is about 60 million mu, the forest land area is 2.55 million mu, and the forest recuperation rate is only 4.25%. Shortage of trees and less trees, less vegetation, erosion ditches, soil erosion serious farmland every year, affecting agricultural development, resulting in low yield, total output instability. In order to speed up the development of agricultural production and ensure a stable and productive harvest with a high yield, it is necessary to strengthen leadership, actively organize manpower and resources, and do well in soil and water conservation. To this end, we conducted a survey on two representative counties, Keshan and Baiquan, from June 28 to July 21, 1981, about the long-term efforts of soil and water conservation. First, the harm of soil and water loss to agricultural production and the post-control effect. Soil and water loss in the region was significantly improved after a period of governance prior to the Cultural Revolution. However, due to the Cultural Revolution, dissolution of soil and water conservation agencies, lack of knowledge and lack of scientific management led to deforestation, deforestation, grassland destruction and destruction of plant communities.
