An analysis was carried out on the seismic activity and the precursory anomaly prior to the earthquakes in Yiliang on September 7,2012. The characteristics of the seismic activity,the dynamic changes of underground fluid and deformation were investigated. As a result of the investigation,we found that: before the earthquake,the seismicity level of M4. 0earthquakes had enhanced,and seismic gap of a small earthquake had appeared; the precursory anomalies emerged about 1 year before the earthquake; there was phenomenon of short-term anomaly migrating from the periphery to the epicenter area; the imminent anomaly appeared in a relatively concentrated period of time, a week before the earthquake. The research has shown a significant guidance for the analysis and prediction of strong earthquakes( Ml> 5. 0).

对1966―2007年正式出版的《中国震例》中云南定点形变异常震例进行统计分析,发现云南地区6级以上地震前均有形变异常,且随着发震时间的逼近,定点形变异常数量有增加趋势。对2000—2015年云南定点形变观测异常进行分析,发现云南及其邻区6级以上地震发生前,定点形变均有显著异常出现。当显著形变异常数量N≥2,1年内云南及其邻区发生6级以上地震的概率可达75%。6~6.5级地震震前形变异常分布的震中距最远为470 km,7级地震达到700 km,且具有震级越大分布范围越广的特征。因此,形变异常台站数量可以作为云南及其邻区有6级以上地震的中短期预测指标。

作为典型的干旱区和生态脆弱区,塔里木河流域是我国粮食、棉花的重要生产基地。水资源、耕地资源与粮棉资源的良性协调发展成为流域可持续发展的关键。通过构建塔里木河流域水-耕地-粮棉系统,测算其发展指数,并以耦合协调度模型测量了系统的耦合程度,在此基础上利用Fractional Logit模型分析了水-耕地-粮棉系统协调发展的影响因素。结果表明:(1)塔里木河流域各系统的发展指数呈现水系统>水-耕地-粮棉系统>耕地系统>粮棉系统。五地州中,巴音郭楞蒙古自治州各系统发展指数排名与流域一致,喀什地区和阿克苏地区在耕地和粮棉系统发展水平领先,水资源系统发展水平靠后,而克孜勒苏柯尔克孜自治州与和田地区则是水系统发展指数位居前列,耕地和粮棉系统发展较落后。(2)流域内水-耕地-粮棉系统耦合协调度介于0.475~0.680之间,处于勉强协调与初级协调之间。五地州中,喀什地区最高,克孜勒苏柯尔克孜自治州最低。这一指标经过缓慢提升后在2017年后明显下降。五地州中,阿克苏地区下降最为明显。(3)水库数量、一般公共预算支出及人口数量是影响水-耕地-粮棉系统协调发展状况的关键因素,三者每增加1个单位将分别引起耦合协调度1.0%、21.0%、35.6%的提升。

新疆作为中国最大的优质棉生产基地,棉花供给对保障我国棉花安全具有重要意义。本研究基于1986—2021年新疆棉花种植面积和价格的时间序列数据,引入目标价格补贴政策,运用Nerlove模型对新疆棉花供给反应进行测度。结果表明,新疆棉花的短期和长期价格供给弹性值分别为0.140和0.369,均缺乏弹性,棉花供给存在时滞性,其种植面积对价格变动不敏感。滞后一期棉花种植面积和棉花价格指数、当期农业生产资料价格指数、目标价格补贴政策对当期棉花种植面积具有显著的正向影响。建议进一步完善棉花市场体系、调整补贴标准、优化棉花质量、加快技术投入。

Science China(Technological Sciences) 2009年第2期52卷 477-483页

作者： SHANG huayan HUANG HaiJun gao ZiYou School of Economics and Management Beihang UniversityBeijing 100083China School of Traffic and Transportation Beijing Jiaotong UniversityBeijing 100044China

The variable message signs (VMS) have been widely used in guiding and managing the dynamic traffic with development of intelligent transportation technologies. It is known that cell transmission model (CTM) can well reproduce such traffic dynamics as shock waves and jams. This paper presents a new method to estimate the route travel times by using the CTM in conjunction with a logit-based route choice rule. The impacts of VMS on a two-route scenario with recurrent and non-recurrent traffic congestion are numerically investigated by analyzing the changes of route flow and travel time. Simulation results show that in networks with suitable long links, the VMS can positively influence travelers' decision making so as to improve the system performance. For non-recurrent congestion, the value space of the route choice parameter that affects the flow distribution between two routes is narrower in the case of high traffic demand than that in the low demand case.

有效应对复杂多变的棉花贸易市场形势、维持棉价稳定对于实现我国棉花产业健康发展、保障棉花安全具有重要意义。本文运用VAR模型,探究棉花进出口贸易与新疆棉花价格间的动态关系,从“贸易-价格”的视角分析棉花发展局势。结果表明:短期内,棉花进口量与新疆棉价是棉花出口量变动的原因,其他情况不存在相互的因果关系;三者之间存在长期均衡关系,但具有一定的时滞性;棉花出口虽一定程度上受其他两个变量影响,但更依赖于自身内力推动。基于以上结论,提出了提质增效、以需定产、优化补贴、贸易保护等发展对策。
