本项以野外调查、采样测试和搜集的地质、水文地质大量第一性资料为依据，在论述盆地的地质构造演化、沉积演化的基础上，以含水系统、水文地质期和水压系统类型的划分和定位为研究的切入点，渗流场、化学场为研究主线，通过建立压实数学模型、砂泥岩恢复厚度数学模型、水岩作用物质成分转移的实验模拟、水文地球化学模拟、地质统计法、类比法、综合分析法等方法，模拟计算了各研究层在各研究时期水循环特点和水交替强度，揭示了各研究层渗流场在地史进程中形成演化的规律性。

By an analysis of the sporopllen time sequences from samples of 38 sections, a discussion of the vegetational and environmental megaevolution in China during the time of 1.6MaBP ～0.8MaBP was made,with the result that we have 2 zones of the sporopollen assemblages and 2 palynoclimate events.

摘 要：通过对已有38个剖面的孢粉时间序列分析，探讨了1.6MaBP～0.8MaBP的植被与环境巨变，划分出两个孢粉带及两个孢粉气候事件，提出该时段是更新世环境最恶劣的时期。

For purpose of analysis structural change of China's fruit supply, this article form a model for China's fruit supply, by virtue of Chow Breakpoint Test, the article divide the 24 years sample into two period, the regressive result show that obvious structural change has taken place in the light of elastic analysis. A conclusion can be drawn that product adjustability and price sensitivity of fruit farmer have improved.

为分析中国水果供给的结构性变化，本文构造中国水果的供给模型，将1978—2001年24年划分为两个时期，利用Chow检验分别回归后发现我国水果供给的各种弹性均发生了明显的结构性变化，从而得出果农对价格的反应能力和敏感性增强、对农资投入的依赖性增强等重要结论。
