摘　　要：利用一级动力学方程对青海农区栗钙土、灰钙土的氮矿化势和矿化速率常数进行测定,结果表明栗钙土比灰钙土有更高的供氮容量,而供氮强度与环境水分条件有较明确的关系。In this essay, we would like to show that we have made use of one - grade dynamic equation to determine Nitrogen reneralization potention and rate of castanozem and sierozem in Qinghai agricultural area. The result indicates that there is higher Nitrogen supply volume of castanozem than sierozem, and Nitrogen supply intensity is closely ralated to conditions of environment and moisture capacity.

关 键 词：氮矿化势 矿化速率 钙层土 青海 供氮速率 土壤
