环塔里木盆地绿洲城市发展与水环境质量协调度

解决好新疆环塔里木盆地绿洲城市发展与水环境质量之间的关系，对"一带一路"倡议顺利实施及新疆社会稳定具有十分重要的作用。基于2004-2017年环塔里木盆地绿洲城市发展与水环境变化状况，构建城市发展与水环境质量的综合评价模型及二者的协调度模型，以探讨环塔里木盆地绿洲城市发展、水环境质量变化及二者的协调关系。结果表明：2004-2017年，（1）环塔里木盆地绿洲城市发展综合指数呈现出逐年稳定上升的趋势，经济发展和城镇空间规模扩大是环塔里木盆地绿洲城市发展的主要形式；（2）环塔里木盆地绿洲城市的水环境质量综合指数呈现出逐年降低的趋势，水环境质量形势严峻；（3）环塔里木盆地绿洲城市发展-水环境质量系统的协调度呈现倒U型的稳定发展趋势，但总体上两者的协调度较低，城市发展和水环境质量之间的矛盾日益突出。

In 1937, the Celestial Mechanics and Cosmogony section of the Sternberg State Astronomical Institute undertook the task of evaluating the Gylden-Moulton hypothesis on the origin of the Gegenshein from the standpoint of celestial mechanics. That investigation, which the authors themselves considered preliminary, contains nonetheless a series of important results. For example, G. N. Duboshin showed that in the planar, circular, restricted three-body problem, periodic motion of finite amplitude in the neighborhood of a collinear libration point is unstable according to Lyapunov's criterion both in the proper and in the orbital sense. The latter result is incompatible with the above named hypothesis, and thus appears as one of the serious objections among the many known negative conclusions relative to the existence of the Gylden-Moulton cluster.Unfortunately, most of the specific problems which arose in the above named research have not been considered since. One of these, the problem of the stability of three-dimensional periodic orbits in the neighborhood of a collinear libration point is solved in the present paper, within the limits of the three-dimensional, circular, restricted, three-body problem. Major attention is given to the investigation of stability in the orbital sense, since in the proper sense all orbits are unstable according to Lyapunov theory. It is shown that in order to resolve the question of stability, it is sufficient to consider the equations in their variational form. Analysis of the roots of the corresponding characteristic equations determines the orbital stability of planar and three-dimensional solutions, which later can be confirmed by calculation of the characteristic exponents appearing in the periodic solutions of the N. A. Artemiev method. Finally, the possibility of conditional stability in the linear approximation is proved.

     

新疆和田河水资源利用与绿色走廊生态建设研究

水是和田河绿色走廊形成与演变最重要的因素。虽然和田河径流量年际变化比较平稳．但年内径流量洪枯季节差异十分悬殊，人工调配水资源的难度较大。随着人类开发利用水资源规模扩大．水资源时空分布格局发生变化，中上游人工绿洲面积扩大，下游绿色走廊植被衰竭，土地荒漠化日趋严重，走廊生态环境持续恶化。文章分析了和田河水资源变化对下游绿色走廊兴衰的影响过程，提出了合理利用水资源、保护绿色走廊生态环境的对策建议。     

地震学家必须开始预报地震

去年，我一直从事某项活动，对于这项活动，有些地震专家认为是荒唐的，有人说是愚蠢的，有人说是真好笑，也有人说是在浪费时间。我做了什么事情会引起如此多同事的这些看法呢?噢，我所从事的活动就是主张进行一些定期的和频繁的地震预报。我公开为新英格兰，并私下为加州的一些同事

巴楚-伽师6.8级地震地质灾害及未来地震地质灾害

2003年2月24日新疆巴楚—伽师交界地区发生了MS6.8地震。地震的发生除了对建筑物及构筑物与水利、交通、电力、电信设施造成了不同程度的破坏外,在地震烈度Ⅶ度以上(包括Ⅶ度)地区产生了不同程度的地震地质灾害。地震地质灾害主要为场地砂土液化、地裂缝与河流陡岸滑塌等类型。随后在新疆巴楚—伽师6.8级地震灾区开展了地震小区划工作,对Ⅶ、Ⅷ、Ⅸ度区进行了场地工程地质条件勘测与综合评价,判定该地区未来可能产生的主要地震地质灾害为场地砂土液化、河流陡岸滑塌。
