The transport from atmosphere is a more important pathway than that from rivers for certain elements and compounds in the remote ocean. The desert and those arid/semi-arid areas in the northwest of China and the Loess Plateau are the sources of those aerosols over the Pacific. atmospheric iron is the limiting factor of the productivity in certain ocean regions. The dust storms must now be seen as repeated sources of pollution elements as well as soil elements to the East China Sea and, farther out, to the North Pacific Ocean and even to the USA. The long-range transport of aerosols, especially the dust storm, from China and the positive feedbacks of iron coupled with sulfur in atmosphere might be one of the important mechanisms that would affect the primary productivity in the Pacific and/or the global climate change and deserve to be further studied. It can be seen clearly that the dust storms would affect not only the health of human beings and the local or regional climate, but also the global climat

Journal of Integrative Agriculture 2003年第9期 67-73页

作者： SHEN Yu 1, HUANG Yao 1,2 , ZONG Liang gang 1, ZHANG Wen 1, XU Mao 3.and LIU Lin wang 3. ( 1College of Resources and Environmental sciences, Nanjing Agricultural University, Nanjing 210095, P.R.China 2institute of {3. physics, chinese academy of sciences, beijing 10002., P.R.China 3.iangsu Agricultural and Forestry Department, Nanjing 21003., P.R.China)

Based on the databases of soils, meteorology, crop production, and agricultural management, changes in the soil organic carbon (SOC) of agro ecosystems in Jiangsu Province were simulated by using a soil organic carbon model with a linkage of GIS. Four data sets of soil organic carbon measured from various field experiments in Jiangsu Province were used to validate the model. It was demonstrated that the model simulation in general agreed with the field measurements. Model simulation indicated that the SOC content in approximately 77% of the agricultural soils in Jiangsu Province has increased since the Second National Soil Survey completed in the early 1980s. Compared with the values in 1985, the SOC content in 2000 was estimated to increase by 1.03.0 g kg 1 for the north and the coastal areas of the province, and by 3.55.0 g kg 1 for the region of Tai Lake in the south. A slight decrease (about 0.51.5 g kg 1 ) was estimated for the central region of Jiangsu Province and the Nanjing Zhenjiang hilly area. Model prediction for 2010 A.D. under two scena rios, i.e., with 3. and 50% of the harvested crop straw incorporation, suggested that the SOC in Jiangsu Province would increase, and thus that the agricultural soils would have potential as organic carbon storage. The incorporation of crop straw into soils is of great benefit to increase soil carbon storage, consequently to benefit the control of the rise of atmospheric CO 2 concentration and to maintain the sustainable development of agriculture.

Measurements of RS and total Ultraviolet radiation （the sum of UV-A and UV-B） from 2005 to 2008 in beijing were used to determine temporal variability of UV/RS and its dependence on water vapor content and clearness index. Results revealed that annual mean UV was 0.3. ± 0.17 MJ m-2 d-1. The highest daily value was measured in May, while the lowest value occurred in December. The monthly mean value of UV/Rs gradually increased from 2.7% in November to 3.7% in August, with annual mean 3.1%. A simple, efficient, and empirically derived all-weather model is proposed to estimate UV from RS. The annual mean daily UV radiation during 1958-2005 was 0.46 MJ m-2 d-1. UV radiation decreased from the early 1960s to the late 1990s but began to increase in the late 1990s. Over the latter half of the 20th century, decrease in UV radiation was 0.018 MJ m-2 d-1 per decade. The decrease trends in long-term annual mean UV radiation of -0.026 MJ m-2 d-1 per year for 1958-1997 and -0.0024 MJ m-2 d-1 per year for 1958-2005. The decreasing trend in UV radiation was sharpest in spring and summer but more gradual in autumn and winter.

A new global three-dimensional transport model of mineral dust aerosols is developed and evaluated. The dust model is embedded in a general circulation model with conservative dynamical core and unique consideration of the polar transportation, which make the model stable in simulations. Comprehensive parameterizations of the emission and deposition processes from wang et al. [2000] are modified to match the surface conditions and meteorological fields of the climate model. A 20-year simulation from the dust model gives an estimation of dust mobilization of 1974 ± 3. Tg yr-1 and a global dust burden of about 25 Tg for the particles smaller than 10 μm. The vertical distribution, temporal variation on different time scales and surface concentration of the simulated mineral dust aerosols are compared with both observations and simulations from other models. The evaluation results show that the new dust model has the ability to reproduce the principal features of global dust transportation. The main deficiency of the model is the underestimation of the dust activity in East Asia during spring and the overestimation of the concentration in Central Pacific, which have also been reported by other model simulations. The global mean optical thickness of dust at 0.63.μm is 0.028 ± 0.004 in the model, which is comparable to the magnitude of sulphate aerosols. Such result indicates that both anthropogenic and natural sources need to be considered when evaluating the climate feedback of aerosols.

CCD and WFI are payloads in the visible light and near infrared bands on CBERS satellites and they have not been applied widely, especially WFI. This article mainly probes into the potential of these two sensors’ application in the vegetation monitoring and analyses the influences of radiometric calibration, atmosphere conditions and sun-observing geometry, etc. on NDVI obtained from these two sensors respectively. In addition it analyses the effect of the spectral response difference of red and near infrared spectral bands in CCD and WFI sensors on NDVI. Results indicate that radiometric calibration is the most important factor on NDVI, which cannot be applied to vegetation monitoring without radiometric calibration. Results also demonstrate that near surface NDVI is different greatly from that of TOA which change with atmosphere conditions. The study shows that NDVI is also affected by the non-lambertian character of surface and the change of the atmospheric path with the observing geometry. And NDVI of WFI is higher than that of CCD. They are very different because of their spectral difference, but they have a good linear relevant relationship.
