%X The change of soil habitat in an area depends on the land-use and cover change in the area to a great extent.Analysis of soil data in north Hebei plateau during last 50 years confirmed that the land-use change,i.e.,the disorder reclamation of a large stretch of natural grassland into cultivated land and the extensive farming,had a series of negative effects on the soil habitat,and made the soil nutrients decreased.During last 50 years,the total and available amount of soil organic matter,N,P,and K decreased by 36.90%,67.77%,44.44%,34.15%,32.22%,58.90% and 35.29%,respectively,and the granulometric contents of sand,silt and clay also varied by 18.24%,19.55%,and 12.29%,respectively,which revealed that in order to ensure the land quality in the regionally important but vulnerable habitat area against the effect of land-use change and its possible degradation with time and to be in sustained dynamic equilibrium,it is necessary to take reasonable fertilization and reliable technical measures.
