Comparative Analysis on Observation Data of the Transfer Station in Nanning National Weather Station

[Objective] The research aimed to analyze difference of the observation data by transfer station in Nanning National Weather Station. [Method] By using observation data (atmospheric pressure, temperature, relative humidity, wind direction and speed, precipitation, sunshine, etc.) from January to December in 2000 at old and new Nanning National Weather Station, difference of the each meteorological factor was contrasted. Main reason for difference of the each meteorological factor was analyzed from altitude, underlying surface property and station environment. [Result] Atmospheric pressure and temperature at new station were both lower than that at old station, while relative humidity and wind speed were both higher than that at old station. Rainfall and sunshine had big differences at new and old stations, but variation did not have rule. Main reasons for obvious difference of the meteorological factor were that altitude, observation environment, terrain and underlying surface property at new and old stations were different. Influences of the altitude and observation environment were especially significant. [Conclusion] The research provided basis for continuity and homogeneity correction of the data sequence at Nanning National Weather Station.

The Seasonal Rainfall Forecast in Nanning City in 2019 with the Method of Trend Comparison Ratio (TCR)

In this paper, the monthly rainfall statistical data of Nanning City, Capital of Guangxi Zhuang Autonomous Region, China, from 2006 to 2018, were collected. On the basis of qualitative analysis of the rainfall seasonal changing law, the non-linear seasonal rainfall forecast model on Nanning City with the method of Trend Comparison Ratio (TCR) was established by the statistical analysis software Office Excel 2013. The model was used to predict the rainfall in spring, summer, autumn and winter in Nanning in 2019. The results were: 286.41 mm, 695.79 mm, 292.20 mm and 118.11 mm, respectively. It was also found that the predicted results were consistent with the seasonal distribution characteristics, annual distribution characteristics and the trend of historical rainfall time series fluctuation, through the qualitative analysis of figures. Compared with the actual measured rainfall data of Nanning City in 2019 in the China Statistical Yearbook (2020), the predicted values are basically consistent with the measured values.

A STUDY ON AIRBORNE ALLERGIC POLLEN GRAINS AND SPORES IN NANNING,GUANGXI ZHUANG AUTONOMOUS REGION,CHINA

The rate of respiratory allergic diseases is high. Statitics show that with the people in the United States, the rate of the diseases caused by pollen grains alone is as high as 10％. The rate of the asthmatic bronchitis is 5％ and it often causes complications. The health and work of people have been highly impaired. Pollen grains are the main aspiratory allergens in atmosphere. Therefore, to effectively prevent, diagnose and cure respiratory allergic diseases, we should, first of all,

Late Oligocene Melia(Meliaceae) from the Nanning Basin of South China and it's biogeographical implication

Melia L. is a small genus of only 2–3 species, which is native to Indo-Malesia, India, Pakistan and southern parts of tropical Africa. Fossil records of Melia are known from the early Miocene to the Pleistocene. Here we describe some mummified fossil endocarps of Melia from the upper part of the Yongning Formation(late Oligocene) in Nanning Basin, South China. These well-preserved stony endocarps are 8–14 mm long and 5–9 mm wide, and have 5 locules with a single spindle seed per locule. We interpret these endocarps as the internal remains of a Melia drupe, and assign them as a new species: M. santangensis sp. nov. This is the only fossil record of anatomically preserved Melia found in China, and also the oldest fossil record of Melia so far reported globally. The fossil record confirms the presence of Melia in Asia at the late Oligocene, and provides evidence supporting the distribution and dispersal hypothesis of the Meliaceae.

Experience of Sponge City Master Plan: A Case Study of Nanning City

As a new urban development pattern, the construction of sponge cities has been deeply integrated into the new urbanization and water safety strategy. Nanning City, as one of the first batch of experimental sponge cities in China, has undertaken exploration and practice on sponge city planning, construction, and management. The sponge city master plan of Nanning City establishes an urban ecological spatial pattern in order to protect the security of the sponge base. The sponge city construction strategy has also proposed an overall construction strategy of a sponge city in line with urban development features. Through the systematic analysis and planning, a "23+10+202" pattern of sponge city construction has been formed. "23" represents 23 drainage basins, in which major sponge facilities such as storage facilities, waterfront buffer zones, wetland parks, ecological rainwater corridor and sponge parks are allocated. "10" represents 10 sponge functional zones, which provide important reference for the establishment of sponge city construction index system. "202" represents 202 management units, which decomposes the general objective and provides technical support not only for sponge city construction and management, but also for the implementation of general objectives in the regulatory plan as well.
