China has abundant crop residues (CRE) that could be used for bioenergy. The spatiotemporal characteristics of bioenergy production are crucial for high-efficiency use and appropriate management of bioenergy enterprises. In this study, statistical and remote-sensing data on crop yield in China were used to estimate CRE and to analyze its spatiotemporal changes between 1990 and 2010. In 2010, Ch...

This study applied multi agent simulation to investigate the impact of farm credit (an agricultural land-use change adaptation strategy) on farm household livelihood. General household and land use data were obtained from 186 sampled household. Two household types were identified; the first household type was better-off in terms of land area cultivated and income generated from rain-fed rice. O...

Spatio-temporal changes in cultivated land have a profound impact on food security and sustainable development. However, existing studies spatio-temporal mostly focus single factors, for instance quantity, quality ecology, that cannot comprehensively reflect the total production capacity sustainability of land. This study aims to construct comprehensive analysis approach provide reference basis...

Porcine reproductive and respiratory syndrome (PRRS) is, arguably, the most impactful disease on the North American swine industry. The Swine Health Monitoring Project (SHMP) is a national volunteer initiative aimed at monitoring incidence and, ultimately, supporting swine disease control, including PRRS. Data collected through the SHMP currently represents approximately 42% of the sow populati...

Because the relationship between cultivated land and surrounding types is not taken into account, there existed a deviation in assessment of landscape ecological security. A novel methodology assessing security presented this study, grid scale adjusted index by disturbance environment index. This method was applied Xintai City, Shandong Province. The results demonstrate that (1) 1985 2015, cons...

To meet the need that real-time access to scientific fertilizer suggestions, and make full use of existing digital resources of cultivated land, a solution is proposed based on WebGIS and fertilization model. With Jinshan county of Hubei province as a case, under the support of spatial database of cultivated land resource, the prescription fertilization system is developed based on MapXtreme an...

The study presented in this paper attempts to evaluate the spatial pattern of soil available phosphorus, as well as the relation between soil available phosphorus and environment factors including elevation, slope, precipitation, percentage of cultivated land, percentage of forest land, percentage of construction land and NDVI using statistical methods and GIS spatial analysis techniques. The r...
