Abstract


Distribution of forest resources for maintaining the ecological environment of a country or region plays an important role in the specific description of the distribution of forest resources from a quantitative point of view , this paper were used on poor economics , mean , standard deviation discrimination , coefficient of variation , and built based on the Gini coefficient the forest resources Gini coefficient index, specific analysis , quantitative calculation method to compare and describe the distribution of six forest inventory of forest resources . Gini coefficient index constructed based on the Gini coefficient of forest resources is the use of the Gini coefficient basic principles and calculation methods , divided into five groups , land area, the cumulative rate of the horizontal axis , the forest area in the cumulative rate of vertical axis Lorenz curve drawing , thereby further calculations. The calculation of the various indicators , and at the same time results , combined with the principles satisfaction indicators for the selection of indicators , compare and analyze their respective strengths and weaknesses at these types of indicators proposed during the description of the distribution of forest resources , we should try to choose the forest resource standard deviation coefficient index as calculated indicators . At the same time , the use of six forest census data calculated distribution of forest resources, the standard deviation coefficient results , pointed out that the distribution of forest resources in China is wavy trends , ie , slightly uniform point distribution of forest resources in some years in subsequent years , but becomes less uniform , the paper went on further analysis of the reasons for the distribution of forest resources such trends . I continue to make use of the method of calculation of the standard deviation coefficient of the distribution of forest resources to analyze and compare the distribution of certain countries or regions of the world within the forest resources , the calculation results of the comparison of several countries and regions , draw , China 's forest resources the distribution is very uneven , compared with other countries or regions . The end of this article , on the one hand , on the causes of the uneven distribution of forest were discussed, but also pointed out that can be solved to some extent of forest resources to the uneven distribution of state , on the other hand , the distribution of forest resources expand research prospects .
