我国在土地资源和粮食生产方面的问题十分严峻:人均耕地面积只有1.5亩,人均草地面积只有5.3亩,人均林地面积只有1.8亩.我国土壤资源的破坏和退化又十分严重:水土流失达150万平方公里,草场退化面积达7.7亿亩,20年来耕地被侵占近4亿亩,等等.要想到2000年达到人均粮食500公斤,则粮食总产需比1984年增加78%.由此可见,任务是何等艰巨.土壤资源的保护刻不容缓.保护土壤资源的首要任务是防止土壤侵蚀与退化,并坚决制止滥占滥用耕地,还应与国土整治、提高土壤肥力、挖掘土地资源和水资源潜力、生态环境研究结合起来.
The problem of land resources and grain production in our country is very serious: the per capita arable land area is only 1.5 mu, the per capita grassland area is only 5.3 mu, and the per capita forest land area is only 1.8 mu. The destruction and degradation of soil resources in our country are very serious again: the soil erosion reaches 1.5 million Sq. Km, grassland degradation area of 770 million mu, cultivated land encroachment of nearly 400 million mu in 20 years, etc. To achieve a per capita food supply of 500 kilograms in 2000, the total grain output will increase by 78% over 1984. Thus, The task is so arduous .To protect soil resources without delay .To protect soil resources, the primary task is to prevent soil erosion and degradation, and resolutely put an end to the indiscriminate abuse of arable land, but also with the remediation of land, improve soil fertility, dig the land resources and water resources potential, Ecological environment research combined.
