光伏场区农林土地综合利用亟需探索局地气候(含农田小气候)特征与变化规律。利用光伏电站自动气象观测系统,基于1个自然年阵列下方种植区、阵列上方、场外对照区逐30分钟连续高精度气象观测数据,开展地-气-农林-光伏复合项目局地气候效应研究。结果表明:光伏阵列显著削弱阵列上方净辐射,阵列下方种植区白昼净辐射为负值,并以有效辐射形式损失热量;阵列下方种植区反照率为0.32~0.45,比场外对照区显著提高;光伏阵列具有增温、增湿作用,日均升温0.23℃,白昼升温最高达0.83℃,日均增湿2%;但是,阵列下方种植区秋季气温日较差降低可高达5.06℃,不利于作物有机质和糖分积累,因此农林复合型光伏土地综合利用需关注阵列下方农田小气候气温日较差的改善。采用静风频率定量识别光伏阵列对风场的影响,结果表明阵列下方和阵列上方静风频率分别比场外对照区提高50%和7%。上述研究成果可为农林复合型光伏项目土地综合利用提供科技支撑。

Acta Metallurgica Sinica(English Letters) 2013年第3期26卷 340-344页

作者： Zhiqing ZHANG Huanhuan XU sainan wu Yin LIU College of Materials Science and Engineering Chongqing University

For a series of Al-0.34／%Mg-1.05／%Si-0.08／%Cu alloys, the effects of pre-treatment on natural aging, bake hardening response and plasticity were investigated using Vickers hardness test and tensile test. Differential scanning calorimetry （DSC） analysis was conducted to reveal corresponding precipitation mechanisms. The results showed that pre-straining and pre-aging alone couldn＇t completely suppress natural aging and improve bake hardening response simultaneously. The sensitivity of the pre-straining and pre-aging on the mechanical properties was evaluated. It was found that pre-aging was the main factor which greatly improved bake hardening response and pre-treatment had a weak influence on plasticity in pre-treated samples. DSC analysis showed that the dissolution trough of clusters disappeared in pre-treated samples, both β”and β＇ precipitation peak shifted to lower temperature and were reduced in pre-strained and pre-aged samples. It was concluded that the formation of Mg/Si clusters was replaced by the accelerated precipitation ofβ” andβ＇ phases, which caused the suppression of natural aging and the improvement of bake hardening response （BHR）.

The Prototethyan Ocean has been suggested as an Early Paleozoic Ocean developed at the Gondwana northern margin. However, its spatial pattern, subduction style and closure time in SW Yunnan and SE Asia still remain unknown. The Prototethyan evolution in SW Yunnan and SE Asia and its internal connection with the South China Kwangsian(Ordo-Silurian)intracontinental orogenesis are also poorly constrained. By summarizing and analyzing the Early Paleozoic geological records in the Sibumasu and Indochina blocks, the eastern South China and SW Japan, this paper proposes the existence of a giant OrdoSilurian igneous belt along the Gondwana northern margin. A preliminary limitation has been obtained regarding the source nature and migration pattern of the igneous belt. Our data allow us to propose a model of the Early Paleozoic Andean-type active continental margin along the East Gondwana northern margin. This is the foundation to determine the southward subduction of the southern branch of the eastern Prototethyan Ocean underneath the Sibumasu and Indochina blocks along the YunxianMenghai(SW Yunnan)-Thailand Peninsula and the Tam Ky-Phouc Son suture in Central Vietnam, respectively, and the eastward linkage with the Early Paleozoic Osaka subduction zone in SW Japan across the peripheral Sanya area. These data synthetically indicate an easterly-diachronous and propagating Andean-type Cambrian(Furongian)-Silurian(Llandovery) orogenesis along the Gondwana northern margin from Nepal, NW India, South Tibet, Qiangtang to Central Vietnam across South Indochina and Sibumasu. This paper reconstructs the Early Paleozoic locations of the Sibumasu and Indochina fragments, as well as SW Japan and South China continent in the Gondwana northern margin, and proposes the far-field effect on the South China Kwangsian intra-continental orogenesis from the subduction of the Early Paleozoic Prototethyan southern branch.

古太平洋俯冲作用在婆罗洲如何表现,有何地质记录?西北婆罗洲与西南婆罗洲是否属于以板块缝合线分割的不同陆块,中生代时期婆罗洲西部与我国东南沿海存在何种关联?回答上述科学问题是揭秘中生代古太平洋俯冲体系的关键一环。本文系统综合了近年笔者在西北和西南婆罗洲所开展的野外调查和代表性火成岩的主微量元素和Sr-Nd-Pb同位素组成、以及锆石U-Pb年代学和Hf-O同位素数据。研究表明,西北婆罗洲发育三叠纪(约256~216 Ma)由少量新生地壳物质参与的基底熔融而成花岗质岩石。沙捞越古晋带(Sarawak Kuching zone)卢帕线(Lupar Line)的帕控(Pakong)和萨拉邦(Sarabang)镁铁质岩石形成于约98~84 Ma,以卢帕线所代表的洋盆主要发育于白垩纪。沙捞越古晋带内前人划属的三叠纪西连组(Serian)火山岩中至少有相当部分与佩达万(Pedawan)组沉积岩系和诗马丹-伦杜-诗里阿曼(Sematan-Lundu-Sri Aman)花岗质岩石同期,为晚白垩世(约95~77 Ma)产物。加里曼丹西北地区原定义为上三叠统—下侏罗统的孟嘉影(Bengkayang)组沉积岩属上侏罗统,莱雅(Raya)组火山岩形成于早白垩世(约144~130 Ma)。同时在加里曼丹西北定义的孟嘉影花岗岩和门西堡(Mensibau)花岗岩基分别为晚侏罗世(~155 Ma)和早白垩世(约140~130 Ma)产物。在西南婆罗洲,以往认为属上古生界的夸扬(Kuayan)组和吉打邦(Ketapan)组为上三叠统—下侏罗统或下侏罗统沉积,其物源为巽他古陆活动大陆边缘产物。原划属变质基底的帕诺杂岩(Pinoh Complex)及默努努(Menunuk)组变火山岩主体形成于早白垩世(约135~120 Ma)。以往填图为喀拉巴(Kerabai)组的火山岩可进一步细分为早侏罗世(~190 Ma)贝特农(Betenung)火山岩组、晚侏罗世(~155 Ma)库达根(Kudamgan)火山岩组和晚白垩世(约102~85 Ma)喀拉巴火山岩组。作为西南婆罗洲主体的苏卡达纳(Sukadana)岩基并非前人划属的晚白垩世,而是至少包含了早侏罗世(~190 Ma)贝拉班(Belaban)岩体、晚侏罗世(约160~150 Ma)门腾巴(Mentembah)岩体和晚白垩世(约87~72 Ma)苏卡达纳岩体的复式岩基。由西北婆罗洲和西南婆罗洲构成的婆罗洲西部至少发育了约200~190 Ma、~155 Ma、约140~125 Ma和约99~77 Ma四期岩浆作用,且空间上自西而东依次年轻,与我国东南沿海地区和南海北部陆架具高度一致性。不论在西北婆罗洲还是西南婆罗洲,其早、晚侏罗世和早白垩世镁铁质和长英质火成岩均有着相似Sr-Nd-Pb-Hf-O同位素组成,以正的或接近零的εNd(t)、太平洋型Pb同位素组成、正的锆石εHf(t)和地幔型δ18O值为特征,他们分别起源于受俯冲组分改造的地幔楔或其新生镁质地壳。沙捞越古晋带晚白垩世卢帕线帕控-萨拉邦镁铁质岩石以高度亏损εNd(t)的MORB型岩石为特征,分布于沙捞越古晋带和南施瓦纳山的晚白垩世镁铁质和长英质火成岩均显示出弧型地球化学属性。研究表明:西南婆罗洲与西北婆罗洲之间缺乏早中生代板块缝合边界,两者一起构成婆罗洲西部,呈北北东向位于巽他古陆印支-东马来陆块之东南缘。进一步的综合对比表明,早侏罗世—晚白垩世期间婆罗洲西部经历了自内而外向东扩展的俯冲增生造山作用,其晚白垩世俯冲边界发育于古晋带卢帕线—中加里曼丹帕朗卡拉亚(Palangkaraya)一带。从婆罗洲西部经我国东南沿海进入日本一线的东亚陆缘发育了中生代的长寿命(>120 Ma)巨型古太平洋安第斯型增生造山带,其俯冲作用于三叠纪—侏罗纪之交(~200 Ma)或更老(早三叠世)即已启动、且具“多阶段俯冲-后撤”特点,直至晚白垩世末期方才转换为现今西太平洋俯冲体系。
