低丘红壤区不同土地利用方式的C值及可持续性评价

C Value of Different Land use Patterns and Its Assessment on Sustainability in Low Hill Red Soil Area

用人工模拟降雨仪研究低丘红壤区不同土地利用方式下植被覆盖与管理因子Ｃ值，并应用Ｃ值对土地利用方式的可持续性进行分析评价。结果表明，合理的土地利用方式，必须有利于降低Ｃ值，提高土壤渗透率，增强土壤蓄水力，以达到减少水土流失和提高经济效益的双重目的。

The vegetation cover and management factor C of soil were studied under different land use pattern with simulated rainfall in low hill red soil area, and the sustainability of the different land use methods using the factor C value was assessed. Results show that the rational land use should be beneficial to decrease factor C value of soil, increase soil penetrability and enhance soil water retention ability in order to reduce water and soil loss and raise economic benefit.
