    In order to investigate the effects of nighttime warming and no tillage on soybean growth and its uptake and utilization of nitrogen (N) and phosphorus (P), field nighttime warming system was designed in trial field in Nanjing University of Information Science and Technology. The experiments were conducted with four treatments, that is, normal nighttime temperature with traditional tillage (CK), nighttime warming with traditional tillage (W), normal nighttime temperature with no tillage (NT), and nighttime warming with no tillage (WNT). The results showed that compared to CK, nighttime warming (W) significantly decreased plant biomass by 6%-25% during the growing season (P<0.05), whereas had little effect on grain yield, grains per plant, grain weight per plant, and 100-seed weight of soybean. During branching and flowering stages, warming reduced N accumulation by 30% and 20%, respectively, and P accumulation by 39% and 39%. No tillage had a limited effect on grain yield and yield components, but significantly decreased plant biomass, translocation amounts and efficiencies of N and P (P<0.01). Warming with no tillage (WNT) treatment significantly decreased plant biomass and grain yield by 29% and 34%, respectively (P<0.01). Moreover, grains per plant, grain weight per plant, and 100-seed weight of soybean were reduced by 22%, 22% and 3%, respectively, under WNT treatment. Meanwhile, at maturity, N and P accumulations were 20% and 22% lower under WNT treatment than under CK treatment, respectively. Thus, this study indicated that grain yield and yield components of soybean were hardly affected by single factor like either nighttime warming or no tillage, whereas nighttime warming with no tillage significantly reduced grain yield of soybean and N and P accumulation.Therefore, it is unfavorable to soybean production by means of no tillage under climate warming condition.

    Spring maize(Zea mays) field experiment of soil water stress and sowing date were conducted in the maize zone of Jilin province in spring of 2010 and 2011, which set 4 soil moisture levels and 3 sowing dates. The soil moisture, irrigation water amount, and rainfall were observed in the period from sowing to 7-leaf, and the leaf age, plant height and biomass dry weight of maize plant were observed after 7-leaf. The impact of soil water change on the state of maize seeding growth was analyzed by using of regression method. The results showed that the soil water stress inhibited the growing of maize leaves and plant, retarded the amassment of seeding biomass. The relationship between relative leaf age of maize seedling, relative plant height and relative biomass and soil moisture in the period from sowing to 7-leaf were significant quadratic function. Every 1 percentage point decline in soil moisture, the maize seedling leaf age, plant height and dry weight decreased 5.5, 5.6 and 11.0 percentage point respectively. Soil moisture in 21.5%-24.0% (or available soil water in 70-85mm) in the period was suitable for maize seedlings growth. If the soil moisture decreased to 18.0%, the maize relative leaf age, relative plant height and relative dry weight dropped to 80%, 85% and 70% from appropriate conditions of 100% respectively. When the soil moisture was below 16.0%, the leaf age, plant height and dry weight decreased to 68%, 70% and 50% respectively. The results had guidance function on evaluation of maize seeding growth, spring drought impact and irrigation.

    Using the meteorological, soil, rice yield and field management data of Jiangsu province as the input data of CERESRice model, the genotype parameters of rice cultivar Xudao no 2 were obtained by calibration and validation processes. Then combined the CERESRice model with the multi model dataset of CMIP3 under the World Climate Research Programmer (WCRP), the impact of the heat injury on the rice yield was simulated by the different high temperature intensity and different high temperature  duration under the 2020s (2011-2040) of A2 and A1B climate change scenarios. The results showed that the CERES Rice model simulated better in Jiangsu province. Heat injury from the booting to heading stage caused a decline for rice production in Jiangsu province under the A2 and A1B climate change scenarios, and the decline rate of rice production reached 17%. When the high temperature intensity was constant, the longer the high temperature duration was, the more seriously rice yield decreased. So as the high temperature duration was constant, the more severe high temperature was, the more serious the heat injury on the rice yield was. So, the rice yield will be decreased by the heat injury from the booting to heading stage under the climate change scenarios. This provides a theoretical support for the reasonable of the disaster prevention and mitigation measures rice production in Jiangsu province.

    Based on ten-day average temperature, precipitation and ten-day NDVI of SPOT data from 1999 to 2010 in north Shaanxi, annual responses of vegetation cover to temperature and precipitation was analyzed by using of the lag cross-correlation method. The results showed that there was strong correlation between NDVI and temperature and precipitation, with the correlation coefficient more than 0.9. The response was promptly over south of Shanbei, with the lag time only ten to twenty days. The correlation coefficient was between 0.75-0.85 across the Maowusu desert sand grass land area, with the lag time thirty to fifty days. NDVI showed a greater correlation and faster response to areas with much water and high temperature. From other perspective, the comprehensively responses to water and thermal factor on basin, loess tableland beam and gully region was better than the gullies rolling loess sub area and typical grassland ecological subregions. The effect degree of temperature on NDVI decreased gradually from south to north, the max  correlation coefficient was 0.947 between bush and temperature, and minimum correlation coefficient was 0.902 in desert. The effect degree of precipitation on NDVI was maximum in farmland, followed by plain grassland and low mountain grassland, and minimum in desert. The correlation coefficient was 0.926 between farmland and  precipitation, and 0.853 in desert. A certain type of vegetation required a higher temperature, also had faster response than others. On the contrary, vegetation depended on low temperature also showed slow response. The response of vegetation cover to annual precipitation was similar to that of temperature. The results could provide a theoretical basis for optimizing vegetation planting types in north Shaanxi.

    Based on cloud fraction and cloud optical thickness data which were retrieved from the satellite data, and cloud decrement ratio which was calculated from the ground observation solar radiation, the various statistical regression and estimate model were established in order to estimate the cloudy ground solar radiation in Fujian. The results showed that the power function was the best function format for cloudy ground solar radiation estimate model in Fujian based on the cloud fraction and cloud optical thickness data(P<0.01), and the solar radiation estimate model had definitude physical reason and rationality. The precision of cloudy ground solar radiation estimate model was validated based on radiation data of 2012 from 66 cloudy observation station. The correlation coefficient was 0.975 between the hour-long solar radiation from estimate model and the hour-long solar radiation from ground observation,the mean relative error was 19%. The mean relative error was 11% for the cloudy ground, when the hour-long solar radiation more than 1MJ·m-2·h-1.The method might estimate cloudy ground solar radiation energy by using fully satellite remote sensing data, and it was abandoned that obvious shortage in the model precision or the model stability of spatial application, when the early solar radiation estimate model was established by using of cloud data of common observation station.The solar radiation estimate model had obvious advantage in Fujian,where was sparse ground observation station and obvious local atmosphere environment characteristic.
