利用生物信息学手段对茶树NAC转录因子家族的成员、系统发育、编码蛋白的理化性质和结构以及创伤胁迫处理后的表达进行分析.研究结果显示,茶树NAC转录因子家族包含49个成员,与拟南芥的106个NAC成员构建系统发育进化树,结果显示,茶树缺乏拟南芥NAC家族17个亚族中的第10和第14两个亚族.理化性质和结构分析显示茶树NAC蛋白质绝大多数是亲水氨基酸,二级结构以无规则卷曲为主,三级结构大部分相似.保守基序分析表明,茶树NAC成员共包含7个保守基序,其中基序3、4、2和5、1分别代表NAC结构域的A、B、C和D亚结构域,而基序7表示的是亚结构域E.第15,16和17亚族的大部分成员都缺失了第2和第4两个保守基序,而第15亚族成员具有一个特异的保守基序6.在机械创伤处理条件下表达模式分析表明,第11亚族的CsNAC33和CsNAC34两个成员虽然具有不一样的蛋白结构域组成,但在应对创伤处理时呈现相对一致的表达模式,而16亚族的CsNAC47和CsNAC48两个成员具有一致的蛋白结构域组成,但其表达模式出现分化.上述结果为后续进行茶树NAC基因家族功能的研究提供了理论依据.

Hydrological models are often linked with other models in cognate sciences to understand the interactions among climate, earth, water, ecosystem, and human society. This paper presents the development and implementation of a decision support system（DSS） that links the outputs of hydrological models with real-time decision making on social-economic assessments and land use management. Discharge and glacier geometry changes were simulated with hydrological model, water availability in semiarid environments. Irrigation and ecological water were simulated by a new commercial software MIKE HYDRO. Groundwater was simulated by MODFLOW. All the outputs of theses hydrological models were taken as inputs into the DSS in three types of links： regression equations, stationary data inputs, or dynamic data inputs as the models running parallel in the simulation periods. The DSS integrates the hydrological data, geographic data, social and economic statistical data, and establishes the relationships with equations, conditional statements and fuzzy logics. The programming is realized in C＋＋. The DSS has four remarkable features：（1） editable land use maps to assist decision-making;（2） conjunctive use of surface and groundwater resources;（3） interactions among water, earth, ecosystem, and humans; and（4） links with hydrological models. The overall goal of the DSS is to combine the outputs of scientific models, knowledge of experts, and perspectives of stakeholders, into a computer-based system, which allows sustainability impact assessment within regional planning; and to understand ecosystem services and integrate them into land and water management.

东部沿海地区是我国多环芳烃排放量最高的地区之一,了解我国东部沿海农村地区大气多环芳烃(PAHs)污染特征和健康风险是大气污染控制的重要基础之一.在本研究中,对青岛农村地区进行了春、夏、秋、冬季的大气PM_(2.5)样品采集,并对其18种PAHs的季节变化、分子组成和与气象要素关系进行了分析,利用总致癌当量毒性(∑TEQ)模型对PAHs进行了健康风险评估.PM_(2.5)浓度季节变化趋势与PAHs浓度季节变化趋势具有一致性,变化趋势为:冬季>秋季>春季>夏季,PM_(2.5)年均浓度为(33.91±28.96)μg·m^(-3),PAHs年均浓度为(11.66±20.00)ng·m^(-3).PAHs(除BkF外)与相应期间内的PM_(2.5)、PM_(10)、SO_(2)、NO_(2)、CO和气压呈正相关性(p<0.01),但是与O_(3)、气温呈负相关性(p<0.01).通过诊断比率计算,表明煤燃烧和机动车排放是农村地区PAHs的重要来源.冬季大气PM_(2.5)中PAHs的总致癌当量毒性(ΣTEQ)超过WHO限值(TEQ 1 ng·m^(-3)),对人类具有明显危害,应对沿海农村地区冬季PAHs的污染给予重视.
