我国的幅员辽阔,自然条件复杂,有广阔的温带,有物产丰富的亚热带,有土壤肥沃的广大平原,有起伏的丘陵,有高低不同的山地,还有号称世界屋脊的西藏高原。无论温带和热带,无论平原、丘陵和高原、山地,到处复盖着不同的土壤,生长着各种各样的植物,有耕地,有林木,还有草地。为了使它更好的为我们出产更多的农产品,就应该合理利用它,充分发挥它的生产潜力。 China has a vast territory, complex natural conditions, a vast temperate zone, a subtropical region rich in natural resources, a vast plain with fertile soil, rolling hills, high and low mountains, and the Tibetan Plateau, which is known as the roof of the world. Regardless of temperate and tropical, regardless of the plains, hills and plateaus, mountains, everywhere covered with different soils, there are a variety of plants, arable land, forest trees, and grassland. In order to make it better produce more agricultural products for us, we should rationally use it and give full play to its production potential.
