大珠母贝人工苗工厂化标粗试验

大珠母贝人工苗工厂化分组标粗；室内养殖５４ｄ，贝苗平均壳高从入池时６．６１ｍｍ增长至１３．０８ｍｍ，最大为１４．２５ｍｍ，平均成活率３１．９％，最高达４９．８％。试验结果初步表明：１．大珠母贝岸上室内工厂化养殖不但可行，而且也将是解决当前海上养成困境的一条出路；２．发现自然海区中也存在饥饿死亡现象及死亡潜伏期，反映出海上养殖高死亡率的复杂性；３．人工配合饲料的应用显著提高了贝苗的增长率和成活率，显示出广阔的商业价值。     

商业化背景下古村落旅游景观生产 ——以安徽宏村为例

以安徽省古村落宏村为例,采用参与式观察和半结构访谈的方法对其旅游景观的生产方式与机制进行研究。结果发现,随着商业化发展,宏村旅游景观生产由原来单一的文物古建保护向更趋复杂化转变,针对3种不同类型的旅游景观采取相应的生产方式。宏村旅游景观生产背后是多种力量参与的生产机制：政府与开发商强强联合,是旅游景观生产的主导力量;当地居民依然扎根宏村,是旅游景观生产的核心灵魂;景区商家热衷于打造“店铺景观”,是旅游景观生产的积极分子;外来游客提出的改进建议则是宏村旅游景观生产的重要参考。4种力量集团本着对各自利益的谋求,彼此间相互合作,影响宏村旅游景观生产的最终结果。最后提出,古村落旅游景观生产需要还原原住居民生活化场景,借旅游商业化发展之势,建立均衡、可持续的景观生产机制与合理的利益分配体系或许是古村落旅游景观生产的正解。     

基于Sentinel-1A的南昌市时间序列InSAR地面沉降监测

本文基于2016-01~2018-07的Sentinel-1A数据,采用PS-InSAR和SBAS-InSAR时序处理方法获取南昌市主城区地面形变信息,对比2种监测结果,分析产生不均匀地面形变的原因。结果表明,2种时序技术的监测结果相关性较高,南昌市主城区的形变趋势为西北抬升、东南下沉。形变区空间分布存在梅岭抬升区、南昌西火车站沉降区、赣江东岸沉降区、邓家埠沉降区和南钢沉降区,主要受地质构造、含水层介质、地下水开采和城市建设等因素影响。     

尼泊尔地区季节性水文负荷对地震活动性的调制作用

利用尼泊尔地区GPS时间序列季节性信号,构建区域季节性三维位移场和应力应变场模型,再结合降水和地震目录等数据,研究该地区季节性水文负荷对地震活动性的调制作用。结果表明：1）季节性地表位移与降水存在较强的时空相关性;2）季风期的降水对断层的长期运动趋势产生扰动,使库仑应力得到一定程度的释放,进而对地震活动产生抑制作用,并影响地震发生时间。     

顾及季节性变化的日本区域加权平均温度建模

利用2014~2018年的ERA-Interim数据建立适用于日本区域的加权平均温度模型,分析其误差并进行季节性改正。结果表明：1）建立的线性加权平均温度模型精度比Bevis模型提高约16%;2）线性模型的残差时间序列存在季节性变化,因此对模型进行季节性改正,改正后的模型精度比Bevis模型和线性模型提高约37%和25%;3）将3种模型与探空站积分Tm进行比较,进一步说明季节性改正后模型的优越性。     

Lacustrine strata sedimentology and lake-level history in ancient Zhuyeze Lake since the Last Deglaciation

The ancient Zhuyeze Lake lies in the east Hexi corridor of Northwest China and it is the interacting belt of the East Asian summer monsoon and the westerly line. The research on paleoclimate of the lake facilitates the understanding of the processes and mechanism of climate change in Northwest China since the Last Deglaciation. Related researches of this area started in the 1960s, and the research on environment changes has become the “hotspot” during the last 10 years. This paper focuses on four sections (Qingtuhu Section, Xiqu Section, Shakengjing Section, Jiutuoliang Section) in ancient Zhuyeze Lake. Much work was done in spot investigation, section strata comparison, geophysical analyses, geochemical analyses and dependable ¹⁴C dating in order to retrieve the dry-wet history of climate changes in ancient Zhuyeze Lake since the Last Deglaciation. The main conclusions are as follows: (1) the highest terminal lake level was 1313–1315 m. In Holocene, the highest lake level was 1308–1309 m occurring between 6700–5800 a B.P.. (2) After geophysical and geochemical analyses, high-resolution records of the climate change since the Last Deglaciation were revealed as follows: cold and dry during 15800–13000 a B.P.; cool and wet during 13000–9500 a B.P.; warm and dry during 9500–6700 a B.P.; warm and wet during 6700–4300 a B.P.; cool and wet during 4300–2700 a B.P.; and at last dry during 2700-0 a B.P.. __________ Translated from Journal of Arid Land Resources and Environment, 2007, 21(12): 161–169 [译自: 干旱区资源与环境]     

Detailed seismicity mapping of the Altai-Sayan zone using large averaging areas

An improved technique is suggested for quantifying seismic activity over averaging areas of an arbitrary size. The example of the Altai-Sayan seismic zone is used to substantiate the choice of a 1° N × 2° E averaging area instead of the traditional one of 40×40 km². Maps compiled with averaging areas of different sizes can be spliced and correlated using a correction coefficient estimated in different models. The new seismicity map of the Altai-Sayan area covers more than 90% of the territory and provides a generalized image of activity being advantageous over the classic maps as it allows better correlation of regional seismicity with the tectonic setting. With larger averaging areas and, correspondingly, a greater amount of data in each area, one can obtain time series of seismic activity to be analyzed using mathematical statistics as a basis for mathematical modeling and simulation of the seismic process.
