137
Cs示踪了陕北安塞试区坡耕地土壤侵蚀量，并以室内分析的方法研究了黄土高原
北部坡耕地土壤侵蚀与土壤性状的关系。研究结果表明，黄土高原坡耕地土壤侵蚀量在
山坡中、上
部是侵蚀最严为强烈的地带，而在坡顶侵蚀较弱，在坡下有土壤堆积;土壤全N、碱解N和
速效K
与水蚀及耕作侵蚀成线性相关;有机质、速效P、阳离子代换量及土壤质地则与水蚀及耕
作侵蚀无
显著相关。

| Abstract: | Soil erosion on cultivated slope land in Ansai experimtnta
l plots northern Shaanxi was deterˉ
mined by
137
Cs tracing method.The relationship between soil erosion and soil pro
perty on northern Loess
Plateau was investigated.The results showed that the erosion in t
he front and middle parts of the slope
cropland were the most fierce belt，which was less in the top o
f slope and soil deposit in the bottom.There
was linear relation between total nitrogen，available nitrogen，and a
vailable potassium and water erosion
tillage erosion; Organic matter，available phosphorus，CEC，and soil t
exture were related to water erosio
and tillage erosion insignificantly. |
