新时期文物管理体制改革探究

文物是重要的文化遗产，是优秀民族传统文化的重要载体，有着重要的历史价值与文化意义。但我国文物管理的现状并不容乐观，存在着管理体制不顺畅、管理体系不健全、监督体系不完善等问题。因此，应深入推进文物管理协调体制、监督机制、保障机制等制度改革，推进文物保护工作的顺利进行。

Effects of Alternative Nitrogen Management Regimes on Production of Eucalyptus in Tropics and Sub-tropics

This paper presents the effects of alternative nitrogen management regimes on production of Eucalyptus in tropics and sub-tropics carried out in autumn, 2011. The aim of the study was to review alternative nitrogen management regimes that could enhance the positive effects and reduce negative effects of different Eucalyptus species in the perspective of smallholders. Literature review was used to survey the alternative nitrogen management regimes on eucalyptus trees. There was a significant improvement （P ≤ 0.01） in mean annual increment （MAI） as measured at seven years of Eucalyptus tereticornis in the plots planted with only legume, pueraria and stylosanthes, compared to that of the control on altitude 150 m and rainfall of 2,000 mm at the age of seven years, The MAI of Eucalyptus urophylla and Eucalyptus camaldulensis in plots planted with beans and rice shows a significant improvement （P ≤ 0.05） over the control treatment. Only the plots treated with nitrogen fertilizer 550 kg/ha showed significant improvement （P ≤ 0.05） in terms of MAI of Eucalyptus nitens, compared to the control treatment. In general, it can be concluded that as these alternative management regimes enhance productivity of Eucalyptus woodlots, the challenge for the small-scale farmers is on how to manage them sustainably. Therefore, forest policies that take consideration of increasing production of Eucalyptus and managing biodiversity with reference to these alternative management regimes should be developed in tropics and sub-tropics.

浅谈我国的不可移动文物所有权

第三次全国文物普查中要求普查者对不可移动文物的所有权进行登录,但在登录时出现了所有权认定不准确现象,由于《文物保护法》中对国有和非国有不可移动文物的不同规定,将给以后的保护工作带来不利的影响。因此,要正确把握不可移动文物的所有权,以便为国家制定相关的文物政策提供参考,为文物保护工作提供依据。
