Supported by RS and GIS, the land use change from 1982 to 2003 were analyzed and the impacts of land use changes on pH value, organic matter, total N, total P, total K, available N, available P, and available K in soil of Xiaojiang watershed, a typical karst agricultural region of Yunnan Province, Southwest China were assessed. The following aspects are concluded. （1） The total land use converted during the past 20 years in Xiaojiang watershed covers an area of 610.12 km^2, of which 134.29 km^2 of forestland was converted into cultivated land, and 210 km^2 *** land was converted into cultivated land. （2） The rapid growth of population and the economic development were the main driving forces of land use change. （3） With the change in land use, the soil properties have been changed significantly. The pH, organic matter, total N, total P, total K, available N, available P and available K in soil in 1982 were 6.3, 38.02 g·kg^-1, 1.86 g·kg^-1, 1.63 g·kg^-1, 10.94 g·kg^-1, 114.42 g·kg^-1, 11.65 mg·kg^-1 and 64.69 mg·kg^-1g, respectively; and those in 2003 were 6.73, 25.26 g·kg^-1, 1.41 g·kg^-1, 0.99 g·kg^-1, 12.6 g·kg^-1, 113.43 mg·kg^-1, 11.11 mg·kg^-1 and 151.59 mg·kg^-1, respectively. Pared samples t-test of the tested indices of soil properties indicate that those indices have changed significantly during the last 20 years. But the soil properties changed differently, due to the differences in land use change. （4） Also, with the change in land use and management measures of soil, the modifications in soil properties which developed from carbonate rocks were more sensitive than those in the soil developed from sandstone.

雅可比是除康德以外另一个德国观念论的重要推手。雅可比对观念论的推动作用至少体现在以下两点:第一,通过重新诠释斯宾诺莎,表明理性唯一合乎逻辑的归宿是斯宾诺莎哲学,以此为德国观念论提供了一个前后一贯的一元论理性体系。第二,雅可比通过发展信仰理论挖掘了斯宾诺莎的平行论,这是一种与认识的反思模型不同的非反思性的认识理论。他的信仰理论将这种模型与个体的自由行动结合起来,以此为观念论的主体理论提供出了非常关键的思想资源。因此,如果人们想要还原德国观念论的形成过程,那么必须将雅可比考虑进来。

在国家重点研发计划项目--"喀斯特槽谷区土地石漠化过程及综合治理技术研发与示范(2016YFC0502300)"的支持下,经过项目组全体成员三年的共同努力,在喀斯特槽谷区生态退化与修复方面取得了一些重要进展。主要有:(1)2000-2015年槽谷区土壤侵蚀总量逐年减少,年平均侵蚀模数逐年降低,槽谷区植被覆盖明显提高;(2)拉巴豆地埂篱根土复合体不仅能有效提高喀斯特土壤的粒径大小和增强土体的抗剪/冲性能,并且能够利用大气N2合成植物生长所需的氮肥,从而提高土壤肥力,可望实现石漠化治理中生态效应和经济效应的双赢;(3)喀斯特槽谷区隧道建设改变了地下水流场并降低了地下水位,进而降低了土壤微生物丰度和多样性,而增加了适应干旱的微生物种群,并导致土壤质量的降低;隧道建设加速了坡面产流和土壤流失,加剧了土地石漠化,从而导致生态退化;(4)随着槽谷区退化生态系统的恢复,生态系统的生态服务功能得到提升。

《精神现象学》中论及的“观察的理性”明显影射理性在近代科学中的表现。黑格尔认为,“理性”在进行“观察”时,并没有意识到自己的真正意图何在,它以为自己在客观地研究物之为物的本质,但它实际所做的事情只是用自己的概念占有自然,只是将自身当作直接存在着的物来寻找。这种意图在“观察的理性”的最后经验中表露无遗:“精神之存在是一块骨头”。然而,在黑格尔的时代,“观察的理性”其实还没有将自己充分展现出来,所以黑格尔并没有真正看到它的最后形态。但根据黑格尔的诊断,这种理性最后一定会将自己表达为直接的物,而他在“头盖骨相学”中看到了这种倾向,因为在这门“学问”中,精神被视为与物直接等同。然而,“观察的理性”的最后经验或许并非“头盖骨相学”,而恰恰就是现代技术,因为当前这个时代正热衷于将精神表达为物。

在《精神现象学》中黑格尔对感性问题做了非常独特的处理。与康德从一种抽象的意识入手不同,黑格尔着眼于现实的感性意识,认为现实的感性意识不是一个抽象的意识结构,而是一种朴素的存在观,即它确信直接性对象的存在。而感性确定性的辩证法自身表明,这只不过是一种偏见,任何存在都是包含中介的普遍者。以此,黑格尔否定了康德关于直接被给予性的提法,从而避免了陷入自在之物的泥潭。

Taking the typical karst agricultural region, Xiaojiang watershed in Luxi of Yurman Province as a research unit, utilizing the groundwater quality data in 1982 and 2004, the aerial photos in 1982 and TM images in 2004, supported by the GIS, we probe into the law and the reason of its space-time change of the groundwater quality over the past 22 years in the paper. The results show：（1） There were obvious temporal and spatial changes of groundwater quality during the past 22 years. （2） Concentrations of NH4^＋, SO4^2- , NO3, NO2^-, Cl^- and the pH value, total hardness, total alkalinity increased significantly, in which NH4^2-, NO3, and NO2^- of groundwater exceeded the drinking water standards as a result of non-point pollution caused by the expansion of cultivated land and mass use of the fertilizer and pesticide. （3） Oppositely, Ca^2＋ and HCO3^- showed an obvious decline trend due to forest reduction and degradation and stony desertification. Meantime, there was a dynamic relation between the groundwater quality change and the land use change.
