| 摘 要： | 气候观测环境代表性和观测资料质量是开展大尺度气候变化监测和研究的前提。为了解我国干燥区气象观测环境变化和台站代表性，作者对河西走廊和北疆九个国家级气象站观测环境开展了调研。本文介绍了调研了解到的情况，并结合先前研究结果，从气候变化监测和研究的视角，讨论了西北干燥区地面观测站代表性问题。目前我国西北地区气象站地面观测，对于干燥区的城市和绿洲区域气候及其变化，具有较高的代表性，但对更广大的荒漠和半荒漠背景气候及其变化，代表性仍显不足。作者发现，早先研究中指出的北疆等地区城镇站地面气温序列负向城市化影响，应与观测场周围局地甚至区域尺度绿洲扩大有直接联系，较难反映绿洲以外干燥区地带性气温变化。针对地面观测环境调研所发现的问题，文章最后提出了几点建议，希望对未来国家基准气候站网设计和建设提供一定参考。

| Abstract: | This article is completed on the basis of the survey of changes in the observational environment of the Hexi Corridor and North Xinjiang meteorological stations in 2021 summer, and it may provide references for the understanding of changes in meteorological observation environment and the representativeness of stations in the Northwest China arid areas and for the design and construction of future national and regional reference climate networks. The survey shows that the current surface observations of weather stations in arid areas are generally representative of the climate and its changes for urban and oasis regions, but are still insufficient in the representativeness for the wider desert and semi-desert areas; the negative urbanization effects on the surface air temperature series of urban stations as previously found in Xinjiang and other arid regions have been affirmed as the results of the expansion of the oasis around the observational sites. It is thus difficult for the observations to really reflect the background surface air temperature changes in the arid areas outside the cities and oases; problem is also obvious in the observational data of extreme weather phenomena after the transition around 2003 from manual to autonomous observations, with some observations of climatic elements and weather phenomena having significant break-points around the transition. At the final section of this paper, a few of suggestions are put forward in response to the above-mentioned problems found in the survey of the ground observational environment. |
