  1. And understanding and studying the spectral features and variation rules of geo - targets in the experimental area, raising that it is the basis of geo - targets information collection with imaging spectrometer data to understand spectral features and variation rules of geo - targets, realizing that in a great extent spectral - integrated - form - based classification method can remove the phenomenon of " different spectrum with same objects " resulted from reflection ratio curve translation because of the angle change among sensor, targets and observation direction, and the average and variance images can be introduced to solve the problem of two kinds of geo - target with similar spectral forms and much different values of whole reflection ratio. it is suggested that " red edge " range bands of vegetation, which has close relationship with vegetation cover and biomass, is the main characteristic bands and important basis for careful vegetation classification and quantitative retrieval, and pixel - based derivative spectral analysis is very useful for removing the effects of soil background values and quantitatively retrieving vegetation biomass and cover. the remote sense quantitative retrieval model is developed for main appraisable factors of desertification monitoring assessment with imaging spectrometer data and then the applicability of model is analyzed

    研究結果如下:首先針對荒漠化地區的地物特徵,對光譜數據不同的數據質量、組合進行了評價,提出了適用於荒漠化監測的基本選擇集;初步了解和掌握了研究地區的地物光譜特性及變異規律,進一步明確了掌握地物光譜特徵和變異規律是用成像光譜儀數據提取地物信息的基礎;發現了基於光譜整體形狀的分類方法在很大程上能夠消除由於傳感器、地物目標觀測方向之間的角變化引起的反射率曲線整體平移的「同物異譜」現象,對于譜形相似而整體反射率的值相差較大的兩類地物,通過引入均值和方差圖像參與分類得到解決;研究還表明在植被「紅邊」范圍內的是進行荒漠化監測的主要特徵,這些與植被生物量和蓋都有密切的系,是展精細植被分類研究和植被定量反演的重要基礎;像元的導數光譜分析可以消除土壤背景的影響,是進行植被生物量和蓋定量反演的有力工具;建立了荒漠化監測主要評價因子的定量反演模型,並分析了模型的適用性。

    該部分內容由第3章構成,即從房地產經濟周期動的一般研究轉到對我國房地產經濟周期動進行分析,從總體上看,改革放以來我國房地產業的真正形成與發展只有20年的歷史,通過對這一短時期中國房地產業發展的探討,指明轉軌時期中國房地產經濟周期動的一些主要特點,同時指出我國房地產經濟周期動形成機制與原因,當前我國經濟轉軌時期,政策周期動是房地產經濟周期動的根本原因,並從理論角分析了房地產經濟周期動與宏觀經濟周期動在各個階間的相互系,得出我國房地產經濟周期相對于宏觀經濟周期動來說在復甦期和蕭條期滯后,但漲期和衰退期卻先行的結論。
  3.
