摘要
耕地是粮食生产的基本要素,是中华民族实现可持续发展的基础。我国障碍退化耕地面积占比已高达40%。耕地数量降低、质量下降,严重威胁国家粮食安全。透过研究耕地的生态环境恶化的原因和特性,可以为提高农田品质、维护自然环境和保持土地健康提供关键性的建议,这也有助于克服如沙漠化、盐渍化、贫瘠等问题所带来的阻碍因素的技术难题,并能根据实际情况来实施改善受损农业生态系统的修复工程。
The Chinese nation’s sustainable development is based on the lifeblood of grain production, culti-vated land. Unfortunately, 40% of this land has been degraded and its quantity and quality have drastically declined, posing a grave threat to national food security. Analysing the sources and features of degraded cultivated land ecosystems has a critical part in advancing cultivated land quality, ecological preservation, and conservation;it is also beneficial to surmount impediments such as desertification, salinity, barrenness, etc., and is of great significance for the restoration of degraded cultivated land ecosystem according to local conditions.
