Currently, the method which is widely used to reconstruct lake paleo-salinity is geochemical characteristics of chemical elements from ostracode shells, boron element method and sedimentary phosphate method; some studies have shown that some biological indicators can also be used to quantitatively analyze paleo-salinity. Although we believe that the palaeo sedimen- tary environment is a closed system, it is still inevitable that it interacted with various environ-mental factors around, which make it hard to obtain information of paleo environment. In order to reconstruct the palaeo-salinity more correctly, we use multi-index method to get a closer to the value of the real environment.","PeriodicalId":171984,"journal":{"name":"Geographical Science Research","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115402253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assessing the effect of land use change on ecosystem service is of great importance for under-standing the disturbance of human activities on local ecosystems. Based on land use data in 1988, 2000 and 2008, the table of equivalent value per unit area of ecosystem services in China, and the economic value of food production per hectare in study areas, the ecosystem services value (ESV) in the Qinghai Lake Region was estimated. It was found that: 1) the area of forestland and grassland continuously decreased while the area of construction land and cultivated land continuously increased. The area of unused land was almost unchanged. From 1988 to 2000, economy devel-opment and agriculture reclamation were the two main factors driving land use changes. The dy-namic indexes of construction land and cultivated land were 0.55% and 0.46%, with an increase in areas of 522.67 hm2 and 7936.65 hm2, respectively. However, the area of forestland and grassland decreased 11,702.74 hm2 and 1203.77 hm2 respectively with the same dynamic index of −0.02%. Since 2000, a series of environmental restoration projects were launched to improve ecosystem and environment. Due to these projects, the increase in area of construction land and cultivated land slowed down, with dynamic index dropping by 0.44 and 0.17 percentage points, respectively. The degradation speed of forestland and grassland was also slower than before, with dynamic index both increased by 0.01 percentage points. 2) The total ESV exhibited an increasing trend in the Qinghai Lake Region, with an increase of 84.13 × 104 CNY and 128.44 × 104 CNY, respectively, compared with that in 1988. Grassland and water areas accounted for over 81% of total ESV in the Qinghai Lake Region. The ESV of construction land, cultivated land and unused land increased by 2341.38 × 104 CNY, 1469.3 × 104 CNY and 34.81 × 104 CNY respectively, while that of forestland and grassland decreased by 2855.65 × 104 CNY and 777.27 × 104 CNY, respectively.","PeriodicalId":171984,"journal":{"name":"Geographical Science Research","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127480482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following the “National Forest City”, three main indexes of urban forest coverage, roads and railways coverage, water and lakes bank coverage are statistics to analyze evaluation index of Kunming urban area and to analyze the forest city construction situation. The results show: First, five phases vegetation coverage map shows that the level of vegetation coverage in Xishan and Guandu forestland coverage area is relatively high, while the level of vegetation coverage is low in Wuhua and Panlong; Second, urban land vegetation coverage level is low, but grassland and forest vegetation coverage level is higher; Last, the indicators of the roads, railways, lakes and rivers reached the standard of “National Forest City” evaluation index. This is due to the fact that a large number of land demands in the urban construction result in part of the grassland and farmland transforming into urban land and indus-trial land in recent years. So this study shows that the urban forest coverage indicators gradually reduce and reach the standard by 2014.","PeriodicalId":171984,"journal":{"name":"Geographical Science Research","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125022429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The correlation between the variation of tropopause temperature and surface temperature, and the correlation between the change rate of tropopause temperature and altitude were also investigated. The results are as followed: 1) Tropopause temperature over the ARNC exhibited downward trends in the last 35a. And the annual and seasonal trends decreased significantly expect for the tendency of spring. The change rate of annual, spring, summer, autumn and winter was 0.51˚C/10a, 0.28˚C/10a, 0.88˚C/10a, 0.53˚C/10a, 0.35˚C/10a, respectively. Ob-viously, the rate of summer was the highest. 2) There were abrupt changes in annual and seasonal tropopause temperature variation. To be specific, the abrupt changes of annual and autumn tro-popause temperature occurred around 1992, and the abrupt changes of summer tropopause temperature occurred around 1994. All the three of them declined after abrupt changes. The spring tropopause temperature had three mutation sites, 1983, 1992 and 1994. The tropopause temperature rose after the abrupt change that occurred in 1983, then declined after 1992 and rose again after 1994. But the average temperature after the abrupt change that occurred in 1994 was still lower than the average temperature before 1983. The abrupt changes of winter tipopause temperature occurred around 1986 and 1988. The tropopause temperature rose after 1986, and declined after 1988. And the average temperature after the abrupt changes that occurred 1988 was still lower than the average temperature before the changes that occurred 1986. 3) There were regional differences in the annual variation and seasonal variation of tropopause temperature. Overall, the variation rate of mountains is higher than that of the basins around the mountains. The spatial variation of annual and summer were similar, and had a banding distribution along northeast-southwest direction. The change rate of tropopause temperature was higher in the region between North Slope of Aljin Mountains and the southeast of Tianshan Mountains than that of the area on both sides.
