    Based on the discussion of the problems of China’s forest park tourism,the paper points out that there are some problems such as inconsistency of management aims of forest park tourism from different management levels,the conflict between public interests and commercial interests,the confusion of improving tourism level and enlarging tourism scale,as well as different interest aims between management and investor of forest park. Through the analysis of the causes of these problems,the paper gives some advices for problem’s solution.

    The implementation of the first phase cropland conversion project in the poverty-stricken area around Beijing has caused the changes of land use,social and economic development and ecological environment in this region significantly. Meanwhile,the people’s livelihood issues in the region has also attracted great attention. In 2013,cropland conversion has entered the second phase. In order to learn about the current situation of the farmers’ livelihoods and the utilization of land in the poverty-stricken area around the capital,a large number of questionnaires and interviews were carried out in the poverty-stricken area and analysis made on farmers livelihoods after their cropland’s conversion and land-use behaviors so as to provide a reference for the sustainable development of local social economy and ecology. The results show that intensive and extensive land uses exsit in farmers’ land utilization, agricultural internal structure has changed from traditional planting industry to comprehensive developmemt consisting of agriculture,forestry,fishery and animal husbandry; the employment of rural labor force has been converted from the first industry to the second and third industries; farmers’ income has been changed from farming oriented to non-farming oriented and income of farm household per year has increased 3.36 times. However,farmers’ livelihood diversification is still in its infancy and there exsit many problems. It still needs the government to pay attention to the public infrastructure of cropland conversion area,improvement of the level of education,strengthening of vocational training,widening the channel of information and promoting credit and cooperation management to realize the sustainable development of farmers’ livelihoods.

    Disturbance was very normal in nature.In order to quantify the extent of forest disturbed,this paper presented a new index called Integrated Disturbance Index,which can be used to express the degree of forest disturbed.Cyclobalanopsis myrsinaefolia mixed stand in Longhushan Forest Farm in Hunan has been taken as an example.And this study indicated that it was disturbed.And the theory of Charles Darwin showed that the intraspecific competition of species is the most intense,so we can make sure that the intraspecific competition of Cyclobalanopsis myrsinaefolia was the main interference factor.So thinning should be done to Cyclobalanopsis myrsinaefolia;Liquidambar formosana Hance and Cinnamomum camphora(L.)Presl were in poor growth because of people’s disturbance and Quercus fabri Hance grew well.

    Through use of richness,evenness and diversity to evaluate species diversity,the concept of Species Diversity Composite Index is proposed,breaking traditional and unilateral limitations of species diversity description.With multiple raw data based on selected indicators and use of CRITIC law the weights are established and each forest Species Diversity Composite Index measurement model developed,which reflects both the diversity indices of traditional information and the actual sample data. This makes the results of the composite index more reasonable and objective.

    Precipitation plays a decisive role,in the maintenance and stabilization of the ecosystem in arid zones.This paper uses geostationary meteorological satellite and ground meteorological data and the Chinese energy water balance monitoring methods to monitor plant environment changes to provide a scientific basis for land desertification dynamic change research in China. Since 2000,the annual average precipitation has in creased in most areas of northern China,the climate is generally warm in arid regions and the ecological environment has improved in some areas. In arid region of North China for nearly 10 years precipitation has slightly risen. The soil moisture index and the precipitation tendency is consistent and the ecological environment is relatively better. In eastern Inner Mongolia,Alashan plateau and Hexi Corridor,precipitation and soil moisture index have slightly increased,increased obviously in northern Qinghai.

    Based on the technology of RS and GIS,the RS image of Landsat TM in 2007 was used as the main data source to obtain the data of land use and erosion of study region. Through the spatial analysis module,the land use and erosion was overlaied to quantitatively analyze the relationship between present state of land use types and soil erosion data.The study results show that the cropland and forestland took an absolute dominate position,which accounted for 90.30% of total area of study region. The soil erosion intensity was mainly low and moderate,while the severe soil erosion exited in some local areas. The area of forestland in wild erosion was largest,while cropland occupied the largest area in light soil erosion. However,the area of unused land in each soil erosion extensity was smallest. Meanwhile,the unused land had no distribution in severe soil erosion.
