农地流转绝不能“不可逆”

农村土地能否自由流转以及如何流转,近几年来在学界和媒体上一直聚讼纷纭,而与此同时,不少地方政府已开始各种不同形式的土地置换操作。其间既有顺利实施的,也有强拆事件频发的。华中科技大学中国乡村治理研究中心主任贺雪峰教授长期从事农村调查,他新近出版了《地权的逻辑——中国农村土地制度向何处去》一书。在他看来,目前盛行的资本介入与地方政府推动的不可逆的大规模土地流转,将使农民退无可退。     

光圈下的红色之旅

没有说出的故事永远胜过已经呈现的情节。这正是这组看似平淡无奇的摄影画面中所蕴藏的法则：还原事物的真实,但永远不停留在拍摄发生的时空里,永远在诉说着一点点关于期待和未来的故事。这,也正是红色之旅所秉承的继往开来之意。     

“微博救父”折射行政权力生态

“明知违法的事情，办了慢慢死，不办马上死。”——何耘韬案揭示了地方土地违法案件中决策者与执行者责任分割的矛盾与困惑，更是对现有行政体制内部政治生态的一次拷问。     

耕耘者 守护神 服务员——衡南县国土资源工作掠影

9年前，这里还冷落荒芜，没有一幢高楼大夏，没有一条水泥马路；9年后，这里已经生机勃勃，引人注目，财富云集、商机云集、人才云集、神话云集。当湘江河畔这座美丽的衡南新县城以惊人的发展速度呈现在人们面前的时候，人们无不感叹衡南县委、县政府拓城的大手笔和大气度。     

Genesis of the Sinian Solid Bitumen and its Significance for Hydrocarbon Accumulation in the Anyue Gas Field of the Sichuan Basin

正Objective Bitumen is generally associated with oil and gas,which was originally used as an indicator of hydrocarbon reservoirs.With the progress of organic geochemical measuring and testing techniques,bitumen,especially solid bitumen sampled from reservoirs,has been proved to be closely related to the evolution of hydrocarbon     

Snow disaster characteristics in Palongzangbu River Basin and mitigation countermeasures for road engineering

The Palongzangbu River Basin contains the highest number of maritime province glaciers in China.There are 130 glacial lakes,64 snow avalanche sites and 28 glacial debris flow gullies distributed within the basin.Snow disasters play a controlling role in the Sichuan-Tibet Highway construction,due to the terrain's special characteristics of high altitude and large height differential.Segmentation mitigation countermeasures for the Sichuan-Tibet Highway are presented based on snow disaster severity level and damage mode of the road.In the Ranwu to Midui section,snow avalanches are regional disasters, so the line should be placed in sunny slopes.In the Midui Gully to Yupu section,the line should be placed in shady slopes and at higher elevations to reduce the risk of glacial lake outburst.In the Yupu to Guxiang section,all three snow disasters are minimal.In the Guxiang to Tongmai section,glacier debris flows are the major threat,thus the road should be placed in shady slopes.     

A Confined Two-peaked Solar Flare Observed by EAST and SDO

The solar flare is one of the most violent explosions, and can disturb the near-Earth space weather. Except for commonly single-peaked solar flares in soft X-ray, some special flares show intriguing a two-peak feature that is deserved much more attentions. Here, we reported a confined two-peaked solar flare and analyzed the associated eruptions using high-quality observations from Educational Adaptive-optics Solar Telescope and Solar Dynamics Observatory. Before the flare, a magnetic flux rope(M...
