To study the influence of winter cold injury on sugar orange industry of Guilin,the chilling injury weather in each county of Guilin planting sugar orange is analyzed,and the disastrous cold weather and its defense measures are studied. Frost,freezing and cold wave happen in Guilin winter sometimes,and the disastrous weather could seriously harm maturing sugar orange or that in the tree,causing peel coke,dehiscent fruit,fruit drop and quality decline. It can effectively reduce the loss by chilling injury and guarantee excellent quantity and high yield of sugar orange by timely understanding weather change information,scientifically managing water and fertilizer,and doing film cover well.展开更多

The research on tourism climate resources of Ziyuan County could provide reference for rational development of mountain tourism in the county. Through on-the-spot investigation,the local tourism and climate data were collected,and the evolution of climate data was analyzed,and the influence of climate on tourism development was studied. It can see snow in winter of Ziyuan County,and there is not high temperature in summer,where is the best place for summer vacation.Due to typical Danxia landform,beautiful mountain ecology and comfortable climate condition,Ziyuan has become the preferred leisure vacation destination of Guilin. It should rationally utilize meteorological service information to effectively avoid the meteorological disasters,and use the climate resource advantage of mountainous area to develop Ziyuan County's tourism.展开更多

Different topographical representative stations were classified into four types of mountain,hill,river and city. Mountain stations were classified into two types,surrounded by mountains and faced with mountains on two sides. Under parallel comparison method,change features of wind direction,wind speed,temperature and haze days at different meteorological observatories were analyzed to investigate the topography influence on haze with pollution increase factors excluded. The study found that the city station had the biggest haze occurrence rate,followed by the mountain station surrounded by the mountains,and the river station had the smallest haze occurrence rate. Urban heat island wind can easily cause urban pollutants concentration around the city center,and the terrain blocking to the wind is not conducive to the spread of pollutants,but the water vapor over the river can reduce the haze.展开更多

The results show that temperature affects the growth of Upu taro most greatly, and sunshine hours and precipitation also influence it obviously. In order to make Lipu taro develop well, it is necessary to utilize climate resources rationally and strengthen the control of diseases and insect pests and field management.展开更多
