Rice is one of the most important staple food crops in China. Climate change is a major contributing factor leading to uncertainty and variability in rice growth. In this paper, we applied linear correlation analysis and multiple regression analysis to analyze the relationships between compound annual rice yield growth rates derived from remote sensing and GIS and climate change rates of temperature,...
Soil organic matter (SOM) content is one of main factors influencing the CO2 exchange between cropland and atmosphere. Therefore, SOM spatial distribution change on cultivated land can have a profound effect on food production and climate change. In this paper, remote sensing and GIS technology were used to obtain the spatial distribution of cultivated land of Northeast China in 2003 through ETM+...
This research is innovative in such aspects as research content, method and so on. Authors took Northeast China as study area, with the help from "3S" technology and based on spatial and temporal land resource data, agricultural statistics data and considering the natural and socio-economic factors. And, this paper analyzed the impact of cultivated land change on the grain production capacity...
Shouyang County which partly locates on the Loess Plateau suffers severe soil and water erosion and is characterized by ecological vulnerability and semi-arid climate. Land suitability evaluation for tree crops is very significant for agricultural production in the ecologically vulnerable regions of semi-arid zone. The authors applied a up scaling approach to carry outland suitability for the four...
Data assimilation is extensively applied in agricultural remote sensing application. However, integration of multi-temporal and high spatial resolution images with crop growth model to evaluate the effect of cold damage on paddy rice was still absent. In this paper, authors applied data assimilation combining LANDSAT/TM, a series of TERRAMODIS images with SIMRIW model to detect how cold damage affected...
Spatially explicit ecosystem services valuation and change is a newly developing area of research in the field of ecology. Using the Beijing region as a study area, the authors have developed a spatially explicit ecosystem services value index and implemented this to quantify and spatially differentiate ecosystem services value at 1-km grid resolution. A gravity model was developed to trace spatial...
