我县地处辽宁省西部,是个六山一水三分团的丘陵山区。全县共有32个乡(镇),50万人口,其中农业人口40万。全县总面积729万亩,其中,山区面积占30.4％,丘陵面积占43.3％。自然气候特点是,地势高寒、无霜期短、土质瘠薄、风沙干旱、水土流失严重。由于自然条件恶劣,所以农业生产水平低。为了改变这种恶劣环境,使山区脱贫致富,多年来,全县人民在党和政府的领导下,进行了坚持不懈的努力,大力开展以植树种草为重点的山区建设。为了治理风沙、防止水土流失,我们把沙棘作为先锋树种,大量栽植。到1986年末全县已有沙棘林45万亩,占有林地面积的18.75％,占全省沙棘面积的75％。
My county is located in the western part of Liaoning Province, is a mountainous and hilly area of three hills. The county a total of 32 townships (towns), 500000 population, of which 400000 agricultural population. The county a total area of 729 acres, of which, mountain area accounted for 30.4%, hilly area accounted for 43.3%. Natural climate is characterized by high terrain, frost-free period is short, infertile soil, wind and sand arid, serious soil erosion. Due to poor natural conditions, agricultural production is low. Over the years, under the leadership of the party and the government, the entire county has made unrelenting efforts to change this harsh environment and made the mountain region become rich and poor. Vigorous efforts have been made to build a mountainous area that focuses on tree planting and grass planting. In order to control the sandstorm and prevent soil erosion, we use seabuckthorn as a pioneer tree species planted in large quantities. By the end of 1986, the county already had 450,000 hectares of seabuckthorn forest, accounting for 18.75% of the total forest area, accounting for 75% of the total area of the seabuckthorn in the province.
