植被遥感在找水中的应用

为了快速、大范围、动态地查明浅层地下水的分布情况,降低传统地面找水工作的风险性和盲目性。从植被和浅层地下水关系入手,根据植被的指示作用,利用遥感技术对研究区域的植被覆盖度进行了定量提取,并综合考虑了地形、地貌和水文的影响,建立了找水远景区预测模型。从实地验证的结果来看,该方法所预测的结果与实际情况基本吻合,具有一定的可行性和实用性,对今后遥感找水工作有一定的参考价值。

Application of vegetation remote sensing in shallow groundwater finding

To quickly, g lobally and dynamically discover the extension of shallow g roundw ater , and decrease risk and blindness of conv ent ional g round inv estig ation, the r elat ion betw een vegetat ion and shallow gr oundw ater w as f ir st ly analysed and based o n the indicatio n of vegetat io n, the technique of r emote sensing w as applied to ex tr act ing the vegetat io n fr act ion in the studied area. Co nsidering the influence of terrain geomo rphy and hydrog raphy , a perspect ive mo del for f inding shallow g roundw ater w as built . T he result s of the spot invest igat ion show that the predict io n of this metho d is co incident w ith the actual satuatio n, so this method has some feasibility, pract icability and reference value in ex plo ring shallow gro undw ater by remo te sensing
