摘要
山东省的西北和西南部分,属黄淮海平原地区,风沙危害十分严重。当地人常说:风起满天沙,风停地搬家。它破坏土地资源,降低土壤肥力;河道淤积,降低排灌效益;沙打禾苗,埋没庄稼;袭击村庄,危害人畜健康。治理措施计有调整农业生产结构,合理利用土地;统一规划,综合治理;防风固沙,营造防护林;积极扩大人工草场,大力发展畜牧业;围堰平种,加强畦田建设。治理前是粮田多,草地少,出力多,收入少,灾多地瘦;治理后是粮田少,草地多,出力少,收入多,林茂粮丰。每年向国家贡献大批粮棉和农林牧副业产品。
The north-and south-west of Shandong Province lies in theHuang-Huai-Hai Plain with very serious endanger ment of sand and wind. It issaid in the locality that rising wind brings sand all over the sky,and thatthe halting wind results in the removing of the land. The consequencefrom that is land resource damaged, soil fertility decreased, river deposi-died, benefits of both drainage and irrigation reduced, crop seedlings hitand covered with sand, villages attacked and the health of man and ani-mal harmed.The suggested measures to harness include adjustmant of ag-fricultural production structure for the land to be utilized rationally,uni-fied plan for comprehensive harness, wind prevention and sand fixed, es-tablishment of protective forest, it is also suggested to expand artificialgrassland actively, to develop animal and husbandry greatly, to cofferdam and level land, to accelarate the construction of small rectangularland. It is found that more crop land, little grassland and great inputproduce little income with much disasters and poor land before the har-ness,on the contrary, after it is harnessed splendid forest and rich har-vest are obtained from less land,more grassland and little input with moreincome. Great amount of grain and cotton and the products from farming,forestry and animal husbandry are contributed to the country every year.
