Kunming belongs to the low latitude plateau mountainous country monsoon climate , because of locating in the western region of yungui plateau , the degree of latitude is low , the elevation is high , there are the wumeng mountains to be as the natural screen in the north , separating the cold air to go down south , the whole area is subjected to influence that come from southwest and warm moisture of indian ocean s flow more , adding there are the plateau lakes to regulate degree of humidity , becoming the four seasons of " summer have no intense heat , winter have no strict and cold " , such as pleasant weather of the spring 昆明属低纬高原山地季风气候，由于地处云贵高原西部，纬度低，海拔高，北部有乌蒙山等群山作为天然屏障，阻隔南下的冷空气，全区多受来自印度洋西南暖湿气流的影响，加之有高原湖泊滇池阳宗海调节温湿度，形成“夏无酷暑，冬无严寒”四季如春的宜人气候。年平均气温为14 . 5 ，最热月平均气温19 . 7 ，最冷月平均气温7 . 5 ，年平均日照时数为2400多小时。
The results show that the relation between the bryoflora of houhe national nature reserve and that of mt . jinfu , shennongjia national nature reserve , jiugongshan national nature reserve is the most closest for their genera similarity coefficients are more than 50 % , which can be explained by the parallel geographical locations and the similar climatic characteristics of the compared areas 这可以从它们所处的地理位置和自然条件加以解释。九宫山保护区与后河保护区处于同一纬度上，同属于亚热带ftewe ’ w硕士学位论文wwgrmaster ’ stlffi徘季风气候，都是北亚热带落叶阔叶林和中亚热带常绿阔叶林的过渡带，气候条件较为相似。
Several characteristics of resources of solar radiation , temperature and precipitation are found out based on grid analysis . the distinct monsoon climate results in the seasonly and regional characteristics of crop producing in viet nam . the high temperature and rain come in the same season ( 3 )根据小网格气候要素栅格图层，分析越南太阳辐射量资源、气温资源和降水量资源的特点，特别是越南季风气候明显，构成了越南农业生产极明显的季节性和区域性特点，雨热同季，适宜扩大喜温高产作物栽培。
It is mountainous area with peak over peak and there are more than 20 peaks with altitude over looom . the reserve is located in the transitional climatic belt between middle subtropical zone and north subtropical zone , with distinct four seasons , cold whiter and hot summer 湖北后河国家级自然保护区位于湖北省西南部的五峰土家族自治县境内，地理坐标位于东经110 29 25 110 40 45 ，北纬30 2 45 30 8 40 。该区地处中亚热带与北亚热带过渡带，属亚热带季风气候。
Tree ring is a kind of natural archives , on which the isotopic analysis is important to study global climate and environmental change . the authors mainly provide a comprehensive introduction to the fractionation models of carbon , hydrogen and oxygen isotope in plants , their research techniques and the extract methods from cellulose . that results show isotopic tracer can record the message of climatic variation and has become a powerful tool for paleoclimate reconstruction and for the modern environment changing research . especially studying on pages , the cellulose isotopic analyses of imbedded old tree ring have become the mainly quantitative means of environmental evolvement . in addition , china is a typical monsoon country , research in tree ring stable isotope seasonal variation can give us a lot of important information on that . up to now , the research techniques and works on tree ring in our country are still in its earlier stage , and remain many limitations . it needs further accumulate basic research materials , intensify regional contrast and intercross studies on relative subjects 尤其是在过去全球变化pages研究中，埋藏古木纤维素中的碳氢氧同位素分析已成为环境演化研究的主要量化手段。另外，对于中国这样典型的季风气候国家，开展树轮稳定同位素随季节性变化的研究具有重要的意义。我国在树轮研究方面起步较晚，研究方法和研究内容上也比较简单，还存在不小差距，既要进一步积累基础资料，又要做区域对比，加强与相关学科的交叉研究。
At first , based on the 272 station monthly precipitation in china , the paper described the heterogeneous of the spatial distribution precipitation by use of the curve of lorenz and the coefficient of g . the results show that the heterogeneous of the spatial monthly precipitation in summer is stronger than in winter . based on this describing , the probability distributions function of the spatial distributions are fitted by use of the gamma distribution model , and this general principle is examined . the results show that the gamma distribution is good on describing the heterogeneous of the spatial distribution precipitation in china 并以分布拟合中国区域月降水量的空间概率分布，拟合效果优良，表明描述中国区域月降水量水平空间分布非均匀性的普适分布律以分布的pdf最为适宜；以1 、 4 、 7 、 10月具有代表性的资料为例分析了各季月降水量空间分布型的主要特征及其形成原因，并从一个侧面表明我国月降水量空间分布的偏态性正是我国降水气候的最显著统计特征之一，这也与我国大陆性季风气候特点密切相关；并且月降水量的基尼系数和分布模式形状参数值都是夏季大于冬季，说明月降水量的空间分布非均匀性夏季比冬季弱。
