This paper analyzed temporal and spatial variation of forest landscape pattern of Wuzhishan city,Hainan province by using some data information including 4 TM Remote Sensing Images (resolution 30m×30m)in 1998,2003,2007,2012 and forest resource inventory & planning in 2010.The result of study indicates that within the 10 years between 1998 and 2007,SHDI has gradually increased,it means landscape types tending to more complete and stable.SHEI first increased later then decreased,and its range of variation is just among a small circle.The result indicated that landscape styles are in uniform distribution without its complexity change.The variance ratio by degree of fragmentation from landscape plaque between coniferous forest and bamboo grove are in high speed and plaque are under heavy damage.Production forest cash tree(arbor),production forest cash tree(shrub),non-forestry land grow well because of the low obstruction.The separating size to forest landscape is on the small side,there is less affection and few reciprocal transformation between plaques.Forest transformed to non-forestry land is the main change of landscape styles.

This paper analyzes the spatial and temporal variations of vegetation coverage in Altay area using the MODIS NDVI data and climate data from 2000—2013 based on the method of trends analysis and correlation analysis.The results showed that1)From 2000 to 2013,Altay area vegetation presents that vegetation NDVI value in the northern region is higher than the southern region,vegetation NDVI value in the mountains and river region is higher than that in desert region distribution pattern; 2)There are some spatial differences of vegetation cover,which shows that in central and southern parts,vegetation increases,the northern region vegetation decreases;3)Vegetation NDVI overall shows a slight increasing trend,the increase rate is 0.002/10 a,there are differences of the NDVI change trend from April to September in growth season.The increase of vegetation coverage was caused by increased meltwater and precipitation under global warming background;4)The correlation coefficient between annual NDVI and the temperature is higher than the precipitation,the NDVI of months in growth season lags behind the temperature and precipitation in 1 to 5 months before.

Based on the data obtained from the survey of 40 samples,we clarified the tree diameter class distribution and types of species,analyzed the species diversity of the plant community in the Confucian Cemetery and evaluated the restoration and succession of plant community.The results are as followsFirstly,in the tree and shrub layers,the Shannon-Wiener diversity index,Simpson diversity index and Pielou evenness index of the Pistacia chinensis forest are obviously higher than those of the Platycladus orientailis forest(P<0.05),but nearly the same as those of the Quercus acutissima forest.In the herb layer,there is no obvious difference among the four indexes(Richness index,Shannon-Wiener diversity index,Simpson diversity index Pielou evenness index).Secondly,there are 7 expansive species,16 seclusive species,2 enhancing invasive species and 3 randomly invasive species.The platycladus orientalis population is obviously lacking in Grade Ⅰseedlings and Grade Ⅱ saplings.The Quercus acutissima population is extremely short of Grade Ⅱ saplings.Thirdly,the main cause of the vegetation status in the Confucian Cemetery is the grass cutting test,while the landscape fragmentation,area effect and non-environmental heterogeneity are also important reasons.
