雪、沙漠、湿地、小麦反射波谱曲线

(1)如图所示,在可见光波段反射率最高和最低的地物分别是                

(2)小麦在       微米之间的波段最容易与其他地物区分开。

(3)利用遥感判断地物的原理是什么 

(4)遥感技术在国民经济应用领域有哪些?(答出两项即可)

答案

(1)雪地  湿地

(2)0.7~0.9

(3)不同地物在同一波段反射率不同,同一地物在不同波段反射率也不同,由此导致其波谱特征不同,根据地物波谱曲线就可以区分和识别地表物体。

(4)资源普查,环境灾害监测等领域。

本题考查遥感的相关知识。(1)通过认真读图可以看出。可见光波段是指0.4-0.76微米之间,该波段反射率最高的是雪,最低的是湿地。(2)小麦和其他地物曲线差别最明显的波段在0.7-0.9微米之间,在这个波段范围内最容易区分。(3)考查遥感的工作原理。遥感是利用遥感器从空中来探测地面物体性质的,它根据不同物体对波谱产生不同响应的原理,识别地面上各类地物,具有遥远感知事物的意思。也就是利用地面上空的飞机、飞船、卫星等飞行物上的遥感器收集地面数据资料,并从中获取信息,经记录、传送、分析和判读来识别地物。(4)考查遥感的应用。经过几十年的迅速发展,目前遥感技术已广泛应用于资源环境、水文、气象,地质地理等领域,成为一门实用的,先进的空间探测技术。

     The Taj Mahal(泰姬陵) is a love story, a sad and beautiful one. If it didn’t exist, we would

easily imagine that the story of its construction was simply a fairy tale. Three hundred years ago,

there lived an Indian emperor called Shah Jahan. His wife was a beautiful and bright woman

whom he loved greatly. Her title was Mumtazl Mahan: its shortened form Taj Mahan, means

“pride of the palace”. In the year 1630 this beloved wife of the emperor died. He was so

broken hearted that he thought of giving up his throne. He decided out of his love for his wife,

to build her the most beautiful tomb that had ever been seen.

     He summoned the best artists and architects from India, Turkey, Persia and  Arabia and

finally, the design was completed. It took more than twenty thousand men working over a

period of 18 years to build the Taj Mahan, one of the most beautiful building in the world.

     The building itself stands on a marble. Platform 29 meters square and 6---7 meters high.

Towers rise from each of the four comers. The Taj itself soars another 61 meters into the air.

It is a eight-sided building made of white marble.

     The emperor planned to build an identical tomb of black marble for himself on the other

side of the river connected by a silver bridge. However his son put him into a prison in the

palace before he could finish, and for the rest of his life, he could only gaze across river at the

tomb of his beloved wife.
