Biodiversity is one of the hot issues of today's biological research, biodiversity formation mechanism and distribution pattern as well as the protection of the use of biology and environmental science research, this article this point, except China (Taiwan ) land as the study area, the data by plant diversity, animal diversity data, geographic factors, climatic factors, energy factor, the MAPGIS MapInfo GIS software, SPSS, DPS and other statistical software and CANOCO ecology software, the land is divided into 241 plots to analyze the environmental characteristics of each region, statistics each region the number of biological diversity, environmental factors and draw the contour map, land seed plant families, genera and species of gymnosperms kinds , fern species, mammals, birds, reptiles, amphibians species contour maps of land plants, animals of the status, distribution pattern and its relationship with environmental factors. Discussed at home and abroad on the concept of biodiversity and the main contents of the biodiversity conservation significance and status of biological diversity and endangered status, the urgency of biodiversity conservation in China. China is a vast and diverse ecosystem types, China is the world's most biologically diverse countries in the world, China is now known more than 30,000 species of seed plants, 581 kinds of mammals, 1244 species of bird, 376 species of reptile, 284 species of amphibian. China is not only biological species, and the unique high degree of biota ancient origin. However, due to China's large population, coupled with environmental pollution, deforestation in the history, destroyed forests and grassland, over-fishing, indiscriminate hunting and other human factors, resulting in biodiversity dwindling number of the country of endangered and threatened species of higher plants about 4500 species, 134 kinds of mammals, 182 kinds of birds, 17 kinds of reptiles, amphibians, higher than the world average. Conservation of biodiversity in China has become imperative to protect the ecological security of China. By the CANOCO package SPSS, DPS and other statistical software analysis, research mainland China plant diversity distribution pattern and its relationship with environmental factors, the results show that the classification and clustering method, the distribution of plant diversity in China can be divided into seven regions, representing plant species richness is very high, relatively high, high, medium, low, low and very low. DCA ordination axis performance of an integrated environmental gradient, that is, from left to right, precipitation, humidity, heat, primary productivity, potential evapotranspiration gradually increased, DCA second axis response to changes in altitude and longitude, that is, from top to , the lower altitude, longitude increases. Plant diversity along the DCA first axis from left to right, showing an increasing trend. The richness of angiosperms and ferns in the first axis of the DCA has the same characteristics of the sort presented logarithmic growth model, changes in gymnosperms richness with increasing hydrothermal conditions change very small, but high-calorie under the conditions of high moisture, richness increased rapidly, showing the power of exponential growth trend. The The DCCA and CCA analysis also shows consistent results and DCA at the same time prove that the decision terrestrial plant diversity distribution pattern of environmental factors is the primary productive forces, and cold index (low temperature) is greater than the diversity limiting high temperatures and years the role of the average temperature. Within a large geographical area, the plant Shanxi University PhD thesis diversity by Latitude greatest impact on plant diversity of the Qinghai-Tibet Plateau has its own unique distribution pattern. Grey Relational Analysis on a time scale, a strong impact on plant diversity is the primary productive forces, the average annual precipitation, relative humidity, January mean temperature potential evapotranspiration these factors change. Distribution patterns of plant diversity research methods to study the the Chinese terrestrial terrestrial vertebrates, mammals, birds, reptiles, amphibians distribution pattern, with TWINSPAN Diversity of Terrestrial Vertebrates 241 cell analysis, is divided into seven Diversity patterns of TWINSPAN figure, from left to right, the number of species of amphibians and reptiles gradually increased, and the distribution of amphibians and reptiles is mainly affected by moisture and heat, so This classification also reflects the trend of the transition to the low-latitude coastal inland by high latitudes, mammals and birds are also an increasing trend. Sort by D D to the first axis and multiple environmental factors showed significantly related, including longitude, with an average annual temperature, annual precipitation, annual average relative humidity, potential evapotranspiration, primary productivity was positively correlated with latitude. above sea level, the average annual wind speed, cold index, average annual sunshine rate was negatively correlated. Diversity of amphibians and reptiles in the first axis of the DCA showing consistent variation of the power of exponential growth model, mammals, birds diversity DCA first axis variation is not obvious. CCA and DCCA, showed that the main factors affecting the distribution patterns of terrestrial vertebrates geographical factors, especially latitude and longitude from the four major categories of terrestrial vertebrates in the first DCA axis distribution and terrestrial invertebrates The DCCA, figure, changes in the distribution pattern of reptiles and amphibians and hydrothermal conditions was more obvious, and the distribution of mammals and birds affected by the longitude and altitude more obvious. Gray correlation analysis showed that the most intense time scales, mammals richness of precipitation in July, with an average annual precipitation, the absolute minimum temperature, primary productivity, relative humidity change. Richness of birds affected by precipitation in July, longitude, relative humidity in July, the average annual precipitation and frost-free period change. Environment variables affect the richness of amphibians and reptiles is the average annual precipitation, primary productivity, the absolute minimum temperature in January mean temperature changes in precipitation in January. Through the area of ??nature reserves and biodiversity research to prove that the natural logarithm of species diversity and protected areas in line with the island geographic biological model. In China, the plant diversity conservation area should be greater than 300Oha animal diversity in protected areas should be greater than 30000ha. Floristic elements of Seed Plants terrestrial tropical flora composition are mainly located at latitude 30 south, this areas of high plant diversity, species ratio is relatively low, diverse habitat types in the mid-latitudes, temperate elements accounted for the majority, moisture conditions are good area, pan-tropical component of the second advantage of component areas with poor water conditions temperate elements of the old world dominants less rainfall, evaporation Northwest Territories, temperate elements account
