我国可耕地面积约为15亿亩(1亿公顷),其中较好的耕地约为4亿多亩。建国以来,由于工业交通及其它建设事业的发展,已占用1亿多亩。约占全部可耕地的7％。就煤炭系统而言,每年新井开工规模以3000万吨计,工业场地以年产原煤10万吨占地1.5公顷计,仅工业场地一项每年就需占地450公顷。工业场地占地多不仅浪费了
Our arable land is about 1.5 billion mu (100 million hectares), of which the better is about 400 million mu. Since the founding of New China, more than 100 million mu have been occupied as a result of the development of industrial transportation and other construction projects. About 7% of all arable land. In the case of the coal system, the annual size of the new well to be started is 30 million tons per year. The industrial site occupies 1.5 hectares of coal with an annual output of 100,000 tons of coal. For industrial sites alone, an area of 450 hectares per year is required. Industrial sites occupy more than just waste
