The Plant Analyse Of Typical Pots In Nanling Mountain And The Determination Research Of Rhodomyrtus Tomentosa

In recent years, the environment problem is going from bad to worse such as the global warming and the frequent occurence of extreme weather. So this thing shoud be pay attention to. People keep working study the climate change and try to find the way to overcome the difficulties. In our study two aspects were studied, including permanent plots for arbor and climate indicator plantRhodomyrtus tomentosa. It can support the basic proof and long term monitor data when the NanLing mountain’s plant influenced by the climate change and the forestry department can set the decent coping strategy. The main content and results are that:We set three permanent plots in TongDao county, JiuLongjiang forest park and JiuLianshan national natural protection area successfully, each one of the permanent plots is1hm2. We researched the species composition and structure careflly.Then researched the arbor particular by measureing the Diameter at breast height(TTD)≥5cm one by oneand numbering them with aluminium brand and locateing the position.The form of community species and biological and ecology characteristics database were established and then we will do once recheck every five years and coupling with the climate change data. It can be an important foundation to studying the potential relationship between vegetation and climate change.Investigated Rhodomyrtus tomentosa community distribution in GuiZhou, HuNan, JiangX, GuangXiand, FuJian province then confirmed the northern front is from25°18’N to26°18’N, deflected to Lianjiang county of FuJian province from Libo county of GuiZhou province.Analysed climate parameters using Standard deviation SD to find the critical climate factors are accumulated temperature and the warm extent in the growing season. On the contrary, the minimum temperature and precipitation have low relativity with its distribution.Used the Bioclim model found that the Rhodomyrtus tomentosa community would be growth in the middle of HuNan and JiangXi province and may be live in the north of ZheJiang province and ShangHai city in the coastal area in the future60years.
