To gain a higher precision of retrieval, the method of pixel information decomposition is introduced in. the method is to divide ground objects correspond to a pixel in to several basic components : soil, vegetation, moisture, water, and ice, and then, using remote sensing data, calculate the contents of every components according to the model by which the component ' s spectrum compose
為獲得較高的反演精度,採取象元組分信息分解的方法,將象元對應地物分解為土壤、植被、水分、水體、雪被等基本組分,然後根據這些組分的光譜組合模型用遙感數據計算象元中各組分含量,再根據組分含量反演半球反射率和反照率。 -
It result in water level rising, hypo - salinification aggravating, sediment silting up, the lake atrophy, marsh extending and nature disaster such as droughu waterlog ^ salinification occurring frequently. completely analysis to geology and hydrology conditions of the district along yellow river in shandong has been applied in this paper and aquifer ' s hydrological characteristic and subsurface flow ' s characteristic have been analysed as keystone in the paper. after finding out the distribution rule and formation conditions of the shallow layer " s ground water resource, divide the district into three hydrological sections according to hydrological conditions and subsurface flow characteristic
本文對山東沿黃地帶地質、水文地質條件進行了全面系統的分析,並重點分析了區內含水層的水文地質特徵及地下水運動特徵,進一步查明了淺層地下水資源的形成條件和分佈規律,根據水文地質條件及地下水運動特徵,劃分出三個水文地質區,劃分並論證了粘土裂隙含水層的形成及供水意義;確定了科學的水文、水文地質參數,為準確地計算淺層地下水資源奠定了可靠的基礎;根據淺層地下水資源形成特點,建立了地下水均衡方程式,據此,計算了區內淺層地下水資源及淺層地下水可采資源。
