发展中国家常常面临牺牲环境换发展的尴尬,处在经济建设高峰的中国,生态环境污染的问题日益突出。目前中国受重金属污染的耕地面积近2000万公顷,约占耕地总面积的1/5,污水灌溉的农田面积达330多万公顷。同样,中国正处于道路建设的高峰时期,大规模的建设需要大量各类土石、化工材料。
Developing countries are often faced with the embarrassment of sacrificing the environment for development. In China, which is at the peak of economic construction, the issue of ecological environment pollution has become increasingly prominent. At present, the area of arable land contaminated by heavy metals in China is nearly 20 million hectares, accounting for about 1/5 of the total area of arable land. The irrigated farmland covers an area of over 3.3 million hectares. Likewise, China is at a peak of road construction. Large-scale construction requires a large amount of various types of earth and stone materials and chemical materials.
