摘要

以库车绿洲为例

探讨了星载雷达影像对表征土壤盐渍化微观离子的响应情况。选取春、秋两季的Radarsat影像数据

野外采集土壤剖面0-10cm和0-50cm处土样

室内测定其8大粒子含量(Na

Mg2+

HCO

)以及pH值、电导率、矿化度、含盐量。采用GPS定位技术

记录每一采样点位的经纬度坐标和雷达影像进行匹配

采用灰色关联分析法分析了RadarsatC波段HH极化对微观粒子在春、秋季节0-10cm和0-50cm土壤剖面的响应。结果表明

春季雷达影像对pH值响应强烈

对含盐量响应不稳定

对电导率、矿化度响应一般。就阳离子而言

对Ca

响应最为显著; 就阴离子而言

对HCO

响应最为显著。10月份雷达影像对pH值、电导率响应强烈

对含盐量响应不稳定

对矿化度响应一般。就阳离子而言

无明显规律。就阴离子而言Cl

响应最为显著

HCO

无明显规律。

Abstract

By taking the Kuqa oasis as a study area

the response of satellite SAR images to the ions of saline soils was analyzed. Two Radarsat images collected in March and October

2001

were selected

and field sampling to soil profiles of 0 -10 and 0-50 cm was made. The values of eight microcosmicions(Na+

K+

Mg2+

Ca2+

Cl-

SO42-

HCO3--

CO32-)

pH value

conductivity

hardness degree

and salt content of saline soils in the typical region were measured according to the measurement point coor dinates in field. The values of each point in the remote sensing images were calculated. The gray associate analytic method was used to carry on the relevant arrangement of eight large ions and the values of the remote sensing images. Results indicated that Radar images in March intensely responded to pH value. The response was unstable to salt content and common to conductivity and hardness degree. For positiveion

the response was most remarkable to Ca2+; and for negativeion

the HCO3- response was most remarkable. Radar images in October intensely responded to pH value and conductivity

were unstable to the salt content

and were middle to the hardness degree. For positive ion

there was no evident rule; and for negative ion

the Cl- response was most remarkable and there was no evident rule in SO42- and HCO3-.
