水生态环境监测是生境保护的前提和基础,针对长江流域水系点多面广、复杂多样、瞬息万变等特点,对监测手段提出了更高的要求。目前,针对大型地表水系的水质监测方式仍以人工取样结合实验室化学分析或现场手持式仪器分析为主,存在方法滞后、手段单一、频次偏低、面源缺失等问题。因此,迫切需要新体制监测技术,突破实时快速、面源定量等现实需求,为长江水系统综合模拟提供可靠数据源。在此背景下,本文提出了一种具有完全自主知识产权的精细光谱探测与计量分析技术,开发了地基、空基等体系技术与装备,在相关项目支持下,开展了体系化技术的示范应用,在长江干流关键断面、三峡示范区和鄱阳湖示范区进行了空—地立体监测,取得了良好效果。监测数据经云平台接入“长江模拟器”,为其综合运行提供了快速实时数据支持,也为未来流域大型水系综合监测提供了新方法和应用典范。

Chinese Geographical Science 2016年第4期26卷 478-494页

Examining the direct and indirect effects of climatic factors on vegetation growth is critical to understand the complex linkage between climate change and vegetation dynamics. Based on the Moderate Resolution Imaging Spectroradiometer(MODIS) Normalized Difference Vegetation Index(NDVI) data and meteorological data(temperature and precipitation) from 2001 to 2012, the trend of vegetation dynamics were examined in the Ziya-Daqing basins, China. The path analysis was used to obtain the information on the relationships among climatic factors and their effects on vegetation growth. It was found that the trends of growing season NDVI were insignificant in most plain dry land, while the upward trends were significant in forest, grass and dry land in Taihang Mountains. According to the path analysis, in 23% of the basins the inter-annual NDVI variation was dominated by the direct effect of precipitation, in 5% by the direct effects of precipitation and temperature, and in less than 1% by the direct effect of temperature or indirect effects of these two climatic factors. It indicated that precipitation significantly affected the vegetation growth in the whole basins, and this effect was not regulated by temperature. Precipitation increase(especially in July, August and September) was favorable to greenness enhancement. Summer temperature rising showed negative effect on plant productivity enhancement, but temperature rise in April was beneficial for the vegetation growth. When April temperature increases by 1℃, the onset date of greenness for natural vegetation will be 2 days in advance. There was a lag-time effect of precipitation or temperature on monthly NDVI for all land use types except grass.

Progress in Natural Science:Materials International 2007年第2期17卷 172-176页

作者： CUI Xueling, TAI Guixiang, ZHANG Hongjun, FANG lin and LIU zhonghui (School of Basic Medical Sciences, Jilin University, Changchun 130021, China) School of Basic Medical Sciences Jilin University Changchun 130021 China

To investigate the mechanism of intracellular signal transduction mediated by activin receptors, the full-length gene encoding a novel activin receptor-interacting protein2a (ARIP2a) was identified from a mouse brain cDNA library. The sequences of ARIP2a and ARIP2, distribution of ARIP2a and ARIP2 mRNA in mouse tissues, and expression of ARIP2a and ARIP2 in activin-induced RAW264.7 cell were compared, and the interaction between ARIP2a and ActRIIA was confirmed. The sequence analysis revealed that the full-length gene of ARIP2a, which composed of 1008 bp and encoded 153 amino acid residues, shared high sequence identity with ARIP2 except the position of the 99th amino acid. RT-PCR assay showed that ARIP2a mRNA was highly expressed in brain, pituitary and testis, and moderately in pancreas and ovary, but undetectable in other tissues. Whereas, ARIP2 mRNA was widely distributed in all mouse tissues that we tested. Moreover, expression of ARIP2a mRNA was significantly decreased in activin-stimulated RAW264. 7 cells; however, the expression of ARIP2 mRNA was increased. Additionally, the interaction between ARIP2a and activin type IIA receptor (ActRIIA) was further demonstrated by mammalian two-hybrid assays and pull-down assays. Taken together, those results indicate that although ARIP2a is homologous to ARIP2, they are different in tissue distribution and responses to activin. ARIP2a could also interact with activin type II receptor as a novel member of ARIP family.

关键词： activin receptor-interacting protein tissue distribution.

植被指数具有明显的季节节律,NDV I时间序列分析可以获取地表植被物候信息,但已有的AVHRR NDV I数据产品仍然存在高噪声,需要进一步校正。在考虑农业植被季节变化特征的基础上,基于先验知识对NDV I时间序列数据傅立叶校正算法进行了改进。利用1992年旬最大值合成1 km NOAA-AVHRR NDV I数据,使用该方法对河北省南部地区几种不同植被类型的NDV I数据进行校正,结果显示:改进的傅立叶谐波校正算法能更好地反映农业植被NDV I季节变化节律,且对自然植被同样适用。对校正后的NDV I时间序列数据进行谐波分析表明:谐波的特征值(谐波余项、振幅和位相)与地表植被动态之间存在相关性,谐波余项表征NDV I时间序列的均值,谐波振幅表征NDV I年内波动幅度大小,不同谐波的位相可以表征NDV I季节变化的时间特征,利用这些参数可以获取地表植被物候信息,并可用于土地覆被和土地利用分类研究以及全球变化研究。
