Much disasters and barren land in the past splendid forest and rich harvest at present—Initiation of the controlling of wind and sand endangerment in Huang-Huai-Hai Plain in Shandong Province
The northand southwest of Shandong Province lies in theHuangHuaiHai 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 deposidied, benefits of both drainage and irrigation reduced, crop seedlings hitand covered with sand, villages attacked and the health of man and animal harmed.The suggested measures to harness include adjustmant of agfricultural production structure for the land to be utilized rationally,unified plan for comprehensive harness, wind prevention and sand fixed, establishment 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 harness,on the contrary, after it is harnessed splendid forest and rich harvest 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.
