近日国土资源部通报2003年度全国土地利用变更调查结果。2003年度全国土地利用变更调查显示建设用地规模随固定资产投资高速增长增大, 补充耕地大于建设占用,占优补劣问题明显。2003年度全国建设占用耕地343.7万亩,灾毁耕地75.6万亩,生态退耕3356.0万亩,因农业结构调整减少耕地497.0万亩;同期,土地整理复垦开发补充耕地466.2万亩。全年全国耕地净减少3806.1万亩,耕地面积由2002年年末的18.89亿亩下降到2003年年末的18.51亿亩,生态退耕仍是耕地减少的主要因素。
Ministry of Land and Resources recently notified the results of the 2003 survey of land use change in China. The 2003 National Survey on Land Use Change shows that the scale of construction land increases rapidly with the rapid growth of investment in fixed assets, and the added cultivated land is larger than the construction occupation. In 2003, a total of 3,447,000 mu of cultivated land was occupied nationwide, 756,000 mu of arable land was destroyed and 33.56 million mu of ecological land was returned. 4.97 million mu of arable land was reduced due to the adjustment of agricultural structure. In the same period, 466.2 mu of cultivated land was replenished for land consolidation and reclamation. In the whole year, the net farmland in the whole country was reduced by 38,061,000 mu. The cultivated area dropped from 1,889 million mu at the end of 2002 to 1,851 million mu at the end of 2003. Ecological restoration of cultivated land is still the main factor of reducing cultivated land.
