Abstract In this paper,soil physicochemical properties were compared between enclosed meadow in shelter belt and desertified meadow of Huang Yangtan Hebei Province,and the effect of enclosure and shelter belt on desertified meadow soil was investigated completely.The soil mechanical composition and soil nutrient can be ameliorated by enclosure and shelter belt,and the average percentage composition of fine sand,sand clay and physical clay have been increased respectively 4.26%,10.20% and 12.08% compared with the desertified meadow,the average percentage composition of total nitrogen,total phosphorus,total potassium,alkali-hydrolyzable nitrogen,rapidly available phosphorus and rapidly available potassium have been increased to 203.65%.
