抗战全面爆发后中国共产党东渡黄河开辟华北根据地,太行是其中重要的一块。面对复杂的政治局面、残酷的战争环境和广大农村的地域传统,中共结合形势发展及政权建设的需要,开展了规模化的调查研究。通过对支部发展状况和群众动员的调查,中共有针对性地作出适时调整,极大地推进了支部的建立巩固,也形塑了良好的党群关系。正是经过战争年代的斗争洗礼,调查研究不仅成为中共普遍性的工作方法,而且因其始终贯穿于根据地的党政建设和社会改造,逐步发展成为具有独特政党色彩的原则理念及社会治理范式。

为了建立稳固的根据地,中国共产党将党的组织深入基层,以获得民众的认同支持并实现资源提取,同时治理、改造乡村,这需要进行有效的政治沟通。在战争时期,土改工作队作为中共介入地方社会的中介组织和机制设置,代表中共意志自上而下地引导甚至监督基层执行中央政策,并自下而上地反馈基层信息、帮助上层调整偏差。其在培养基层干部、动员民众、协调干群关系等方面发挥着重要功能,夯实了基层的党组织,维护了党在基层的权威。工作队的设置促进了政治信息的流动传播,形成了有效的政治沟通,有助于消除政府与民众之间的隔阂,强化民众的政治认同,由此促成中共对地方的有效治理,加强基层政权的建设和政治整合。

Variations of Surface Heat Fluxes over the Tibetan Plateau before and after the Onset of the South Asian Summer Monsoon during 1979–2016

As the "Third Pole of the World," the Tibetan Plateau (TP) is an important thermal forcing to the South Asian summer monsoon (ASM) and even the global atmospheric circulation. In this paper, surface heat fluxes from the ERA-Interim reanalysis data during march-October of 1979-2016 in the TP and its surrounding areas are examined and analyzed. The results are as follows.(1) From march to may (before the ASM onset), the main body of the TP is dominated by sensible heat flux, which increases rapidly with high (low) values in the west (east), while the change of latent heat flux is small but it increases with time.(2) From June to August (after the ASM onset), sensible heat flux over the TP decreases, while latent heat flux increases rapidly with high (low) values in the east (west).(3) From September to October (after the ASM withdrawal), sensible and latent heat fluxes are comparable to each other in strength, again with high (low) sensible heat flux in the west (east).(4) During 1979-2016, surface sensible heat flux in the whole TP shows a slightly downward trend, while latent heat flux shows an increasing trend. Specifically, in the western TP, sensible (latent) heat flux shows a weak decreasing (an increasing) trend;while in the eastern TP, sensible (latent) heat flux decreases (increases obviously). These variations are consistent with the observed warming and moistening in the TP region. The above results are useful for further analysis of the change of atmospheric heat sources and surface heat fluxes over the TP based on the data from the Third Tibetan Plateau Atmospheric Science Experiment (TIPEX-Ⅲ).

Comparison of Different Generation Mechanisms of Free Convection between Two Stations on the Tibetan Plateau

Based on high-quality data from eddy covariance measurements at the Qomolangma Monitoring and Research Station for Atmosphere and Environment（QOMS） and the Southeast Tibet Monitoring and Research Station for Environment（SETS）,near-ground free convection conditions（FCCs） and their characteristics are investigated. At QOMS, strong thermal effects accompanied by lower wind speeds can easily trigger the occurrence of FCCs. The change of circulation from prevailing katabatic glacier winds to prevailing upslope winds and the oscillation of upslope winds due to cloud cover are the two main causes of decreases in wind speed at QOMS. The analysis of results from SETS shows that the most important trigger mechanism of FCCs is strong solar heating. Turbulence structural analysis using wavelet transform indicates that lowerfrequency turbulence near the ground emerges from the detected FCCs both at QOMS and at SETS. It should be noted that the heterogeneous underlying surface at SETS creates large-scale turbulence during periods without the occurrence of FCCs. Regarding datasets of all seasons, the distribution of FCCs presents different characteristics during monsoonal and non-monsoonal periods.

The Regional Surface Heating Field over the Heterogeneous Landscape of the Tibetan Plateau Using MODIS and In Situ Data

In this study, a parameterization scheme based on Moderate Resolution Imaging Spectroradiometer （MODIS） data and in-situ data was tested for deriving the regional surface heating field over a heterogeneous landscape. As a case study, the methodology was applied to the whole Tibetan Plateau （TP） area. Four images of MODIS data （i.e., 30 January 2007, 15 April 2007, 1 August 2007, and 25 October 2007） were used in this study for comparison among winter, spring, summer, and autumn. The results were validated using the observations measured at the stations of the Tibetan Observation and Research Platform （TORP）. The results show the following：（1） The derived surface heating field for the TP area was in good accord with the land-surface status, showing a wide range of values due to the strong contrast of surface features in the area. （2） The derived surface heating field for the TP was very close to the field measurements （observations）. The APD （absolute percent difference） between the derived results and the field observations was 〈10%. （3） The mean surface heating field over the TP increased from January to April to August, and decreased in October. Therefore, the reasonable regional distribution of the surface heating field over a heterogeneous landscape can be obtained using this methodology. The limitations and further improvement of this method are also discussed.
