THE REMEDIATION METHOD OF SANDY LAND IN THE FELDSPATHIC SANDSTONE AREA - A REVIEW

Full text

This review presented a remediated technology that sand was remediated by feldspathic sandstone to convert to usable land and synthesized formation mechanism of remediated soil (sand remediated by feldspathic sandstone), highlighting the effect of remediated soil on the agriculture as well as pointing out the effect of sand stabilization of remediated soil. This paper could be helpful to guide the remediation method on sandy land where feldspathic sandstone was associated with sand and widely distributed, such as Mu Us feldspathic sandstone area, as well as to suggest useful avenues to improve the physical and chemical properties of the sandy land which was favorable for sustainable crops growth. Sand remediated by feldspathic sandstone, could be fixed, and soil erosion could be effectively prevented as well as its surrounded ecological environment could be well protected. This research has important theoretical and practical significance in the feldspathic sandstone area, for the sand remediated by feldspathic sandstone is proved to be a sustainable way to comprehensively improve the sandy land, and to solve soil erosion problem in feldspathic sandstone areas with remarkable economic, social and ecological efficiency.
