吉林省西部地区风沙很大。其中主要的12个县市,解放后经过多年努力,已治理风蚀面积约44.4万公顷,占原风蚀面积的82%。这对减轻该区的风沙危害,改善生态环境和提高农业生产水平,都起了重要的作用。不幸的是,这个地区经历了3年经济困难时期的破坏,长期“左”倾错误的折腾和十年内乱的干扰,使风蚀面积从解放初期的54.2万公顷剧增到近几年的140多万公顷。除去前两年停耕严重风蚀地近22万公顷外,还有亟待治理的沙荒面积119.5万公顷。这些风蚀面积,多数是流动沙丘。它们每年以20米的速度向村镇涌进。许多庄户人家的庭院内堆沙1米多高,掩埋了大门。由于“三料”奇缺,当地居民生活非常穷困。主要治理措施如下: 1、合理利用土地,改广种薄收为精耕细作; 2、大力植树种草,积极发展农村能源,全面防治风沙危害,有效地改善生态环境; 3、推广户包治理,认真落实政策,提高防治风沙的效益,加快治理风沙速度。
The wind and sand in the western region of Jilin Province are quite large. Among them, 12 major counties and cities, after many years of liberation, have managed 444,000 hectares of wind erosion, accounting for 82% of the original wind erosion area. This has played an important role in alleviating the harmful effects of wind and sand in the area, improving the ecological environment and raising the level of agricultural production. Unfortunately, the region has experienced three years of economic downturn, the long-term “leftist” mistakes and decade-long civil disturbances, causing the area of wind erosion to soar from 542,000 hectares in the early days of liberation to over 140 in recent years Ten thousand hectares. In addition to the last two years to stop severe wind erosion nearly 220000 hectares, there are urgent need to control the 1191900 hectares of sand wasteland. Most of these wind erosion areas are mobile sand dunes. They pour into the townships at a rate of 20 meters a year. Many dwellings in the yard of a man dwell 1 meter tall and buried the door. Due to the scarcity of “three materials,” local residents are in a very poor condition. The main control measures are as follows: 1. Rational use of land and reform of thin income for intensive cultivation; 2. Vigorously planting trees and grass, actively developing rural energy resources, comprehensively controlling the hazards of wind and sand and effectively improving ecological environment; 3. Promoting household management, conscientiously implementing policies, Improve the effectiveness of wind and sand prevention and control, accelerate the speed of wind and sand control.
