人造耕地的目的
Purpose of Artificial Cultivated Land
( ACL )
    我们搞人造耕地的根本目的是解决我国的粮食自给问题。
    在我看来,在中国最重要的事情是老百姓的吃饭问题,在中国最宝贵的东西就是粮食。在我国的历史上,第一个产粮高峰是 1998 年,为 5.12 亿吨。实现了粮食自给有余,农民卖粮难,仓库装不下,这是一个历史性的胜利。然而,事情的发展不尽人意。自从 1999 年我国开始成为净粮食进口国以来,我国的粮食产量已经是连续 8 年低于 5 亿吨。 2007 年达到 5.02 亿吨,以后逐年增加, 2010 年为 5.46 亿吨。现在有一个不能回避的现实是,中国的粮食已经不能自给。目前,我国粮食自给率波动在 90% 至 95% 之间﹙日本为 40% ﹚,而且每年以 0. 5 %至 1 %的速度在减少 。依 赖进口粮食满足国内粮食需要,其风险性极大,粮食安全问题将要长期困扰着我们。     在这样的背景情况下,我认为只有搞人造耕地,才能解决我国的粮食自给问题,才能彻底地解决老百姓的吃饭问题。别的方法都靠不住,包括单纯地依赖高产种子、转基因农作物和提高单位面积粮食产量。
 
人造耕地的目的
Purpose of Artificial Cultivated Land
( ACL )

The purpose of trying to produce artificial cultivated land is to solve the self-sufficiency in grain problem in China .
In my opinion, the most important thing in China is food for its people, so the most valuable thing in China is grain. In Chinese history, China saw its first peak grain production in 1998 with 512 million tons, realizing the self-sufficiency in grain and even enjoying some surplus. In that year, it was difficult for the farmers to sell their grain and the barns could not store all the grain, which could be called a historical success. However, things did not turn out satisfactorily all the way. Since 1999 when China became a net grain import country, our grain production had experienced the output of less than 500 million tons for 8 consecutive years. In 2007, the grain production reached 502 million tons and it increased gradually year by year. In 2010, it reached 546 million tons. We are faced with an unavoidable fact, which is that our grain production can not meet the demand in China . At present, the degree of self-sufficiency in grain stands at 90% - 95% in China (40% in Japan ), and it is decreasing by 0.5% -1% year by year. It is very risky to rely on imported grain to meet the internal need, so China will be perplexed by the issue of grain security for a long time to come.
Against such a background, I think the self-sufficiency in grain in China can only be guaranteed by producing artificial cultivated land so that the food problem of the people can be solved completely while the other alternatives, including relying on high yield seeds, GM crops and increasing the per unit area yield of grain are not reliable.
