摘要
采用相对土壤质量指数法,对河北省季节性休耕试点区、对照区的耕地质量进行评价.结果表明:河北省休耕区域与对照区域相对耕地质量指数均有所提高,且休耕区的相对耕地指数提升速率明显高于对照区.持续推行休耕政策可以有效改良休耕地区的土壤质量,促进该地区耕地土壤地力的恢复与提高.
Abstract
The relative soil quality index method was used to evaluate the cultivated land quality in the pilot and control areas of seasonal fallow in Hebei Province.The results showed that the relative cultivated land qual-ity index of the fallow area and the control area in Hebei Province had improved,and the improvement rate of the relative cultivated land index of the fallow area was significantly higher than that of the control area.The continuous implementation of fallow policy can effectively improve the soil quality in fallow area and promote the restoration and improvement of cultivated soil fertility in this area.
