TL;DR: Based on the grassland survey and remote sensing technology, the ecological types and their spatial distribution of grassland, the features of grass land resources and their utilization in the source regions of Yangtze and Yellow rivers were studied as discussed by the authors.
Abstract: Based on the grassland survey and remote sensing technology, the ecological types and their spatial distribution of grassland, the features of grassland resources and their utilization statues in the source regions of Yangtze and Yellow rivers were studied The production capacity of the grassland was estimated By the regional eco-environment investigation and three periods' remote sensing information, the eco-environmental changes of the grassland in recent 40 years were analyzed Those results showed: (l) The types of grassland in the study area were mainly the high-cold meadow and the high--cold steppe The high-cold meadow was one of the most important grassland types in the study area, could be divided into four sub-types: high-cold typical meadow, high-cold swamp, high-cold steppe meadow and high-cold shrub meadow The high-cold meadow area was about 5378% of the whole study area (2) The coarse protein contents of the main forage grass were over 10%, and the coarse fat contents over 2%, and the energy reserves over 934 kJ g-1 (3) Since 1970s, because of the rapidly improvement of livestock husbandry the grazing over the cold season pastureland was very heavy with the l-5 fold larger than the theoretical carry capacity The most of the warm pasturelands were over grazing too Those resulted in the seripusly degradation of grassland with the annual degredating rate of 664% -3445% Rodent damages also play an important role in the ecological degradation It was the most urgent need in the source regions of the Yangtze and Yellow rivers to rationally utilize the grassland resources and to study possible rehabilitation measures for the eec-environment of the regions so as to ensure a sustainable development

TL;DR: The data about sand-dust storms in Northwest and North China from 1952 to 2000 have been analyzed to get a comprehensive knowledge of distribution of sand dust storms in China and to further understand their changing features and recent tendency as mentioned in this paper.
Abstract: The data about sand-dust storms in Northwest and North China from 1952 to 2000 have been an-alyzed to get a comprehensive knowledge of distribution of sand-dust storms in China and to further under-stand their changing features and recent tendency. The sand-dust storm original sources in Northwest andNorth China mainly distribute in three regions: Hexi Corridor of Gansu Province and Alxa Plateau,south- ern rim of South Xinjiang Basin and central Inner Mongolia. The features on frequency variation of sand-dust storms in recent 50 years are as follows: a fluctuating increase during 1960s-1970s, a fluctuating de-crease during 1980s-1990s and a rapid increase after the year of 2000. In the future, sand-dust stormsmay enter a new active period. The variation of sand-dust storm activities has a close relationship with thedecadal changes of East Asia atmosphere circulation and changes of ecological environment.

TL;DR: A time series of SPOT-VEGETATION Normalized Difference Vegetation Index (NDVI) data with 1 km×1 km spatial resolution were used to monitor the vegetation cover change during the period of 1998 to 2004 in Northwest China as mentioned in this paper.
Abstract: A time series of SPOT-VEGETATION Normalized Difference Vegetation Index(NDVI) data with 1 km×1 km spatial resolution were used to monitor the vegetation cover change during the period of 1998 to 2004 in Northwest China.The MVC(Maximum Value Composites) method and the linear regression were used to characterize the trends in vegetation cover change.And the landuse map of Northwest China was used to analysis the NDVI variety of different landuse types.During the last 7 years,the vegetation degradation was popular in most regions of Northwest China. However,there were some regions where vegetation cover was increasing,but the increasing range was smaller than the decreasing range on the whole.The results indicated that the improved regions of vegetation cover mainly appeared in the major part of Shaanxi and Ningxia province and in the northwest and southeast parts of Xinjiang.But in the most part of Northwest China,the NDVI was reducing.However in the same particular year,the patterns of NDVI variety of different vegetations were in the similar tendency.

TL;DR: Based on a brief review of the studies and results on the definition of desertification in China and foreign countries and according to our researches and combating practices on land degradation in the North of China, we think that the sandy desertification is land degradation characterized by wind erosion mainly resulted from the in\|coordination between human impact and natural conditions in the arid, semiarid and some sub\|humid regions as mentioned in this paper.
Abstract: Desertification is land degradation, which is composed of sandy desertification, water erosion and salinization. Among of those the sandy desertification is a main process of land degradation in the North of China. Based on brief review of the studies and results on the definition of desertification in China and foreign countries and according to our researches and combating practices on land degradation in the North of China, we think that the sandy desertification is land degradation characterized by wind erosion mainly resulted from the in\|coordination between human impact and natural conditions in the arid, semiarid and some sub\|humid regions. We also discuss the time, space, cause, landscape, trend and disaster during the process of sandy desertification. We distinguish desert and desertified land from formation and evolution in different time\|space, causes, processes and utilization/combating, and note that desert was controlled by climatic changes and human activities should bear the responsibility for sandy desertification.

TL;DR: Wang et al. as mentioned in this paper conducted a field investigation and monitoring with remote sensing to the desertification status in 256×10-4-km area of Northern China, and the results showed that the total desertified land area had increased to 38.576×10 -4 -km from 33.8 -km.
Abstract: It was disclosed by former researches that the desertification land in northern China developed at rate of \{1 560\} km2 per year from late of 1950s to middle of 1970s, and till late of 1970s the already desertified land had reached 17.6×104 km2, the light degree and potential desertification lands had reached 15.8 104 km2; During the following ten years the developing rate was up to \{2 100\} km2 per year, and till late of 1980s the already desertified land had reached 33.3×104 km2. In order to further disclose the status and developing trend of desertification land in China from then on and provide dependable bases for the strategy making of desertification control, another field investigation and monitoring with remote sensing to the desertification status in 256×104 km2 area of Northern China was conducted in 2000. The results showed that the total desertified land area had increased to 38.576×104 km2 from 33.895×104 km2 in 1987 , among which the light degree and potential desertification land was 13.93×104 km2, occupied 36.1% of the total; the middle degree was 9.977×104 km2, occupied 25.9%; the serious was 7.907×104 km2, occupied 20.51%; the very serious was 6.756×104 km2, occupied 17.5%. The developing rate of desertification land was further raised to \{3 500\} km2 per year during 1990s. In details, although the desertification in part of agricultural and agro\|pastoral areas inversed distinctly, the area of desertification land in desert steppe and steppe desert continuously extended and the degree intensified.
