The Renewable Power Technology Training Course is described in the article which was developed by Renewable Power Technology training lab of State Grid Technology College. The course has been developed to train all new staff of the State Grid and was building in block designed. The blocks were in various forms, including theory, video, and training. The feedback information indicates that the course content can satisfy the job needs of the trainee, the form of design is reasonable. The training effect has been unanimously certificated by the trainee.
The Vegetation Characteristics Model is based on the principle of DTM. The property values is the data of forest coverage of every small spot of forestry, By spatial interpolation, we can access continuous, accurate characteristic values of the data model which covers the entire forest farm forestry. This article describes three interpolation methods in detail. They are used to build Vegetation Characteristics Model, are compared each other. we can get the final conclusion: Inverse distance weighting method produces samples of the surface does not exceed the maximum and minimum data; if less sample points, using the Kriging interpolation method, we need to add some sample points in those changing areas; Spline, the main problem is when the area is lack of data, then there will be “steep slopes”, it is often referred to as "overshoot" ,this model does not work effectively. The Vegetation Characteristics Model can simulate the surface of the real situation in the forest region. This model can support spatial data for Forestry production, management and spatial analysis.
Based on Vegetation Dynamics Development Tool (VDDT), the 100(1989-2089) years forest landscape dynamics in the western margin of Sichuan Basin under 3 scenarios were simulated. Management measures such as closing the land for reforestation, forestation, stand improvement, reinforcement planting can increase forest land area, reduce open forest land area,suitable land for forest and shrub land.Artificial Cryptomeria fortunei plantations get more negative influences from rodent damage than artificial Cunninghamia lanceolata plantations. After earthquake, rodent damages intensity and frequency increased, suitable land for forest and unused land first increased and then decreased, forest land first decreased and then increased; forest land decreased and unused land increased in 2089, compared with the scenario without rodent damage or earthquake.
Based on multi-spectrum satellite remote sensing (RS) images and GIS, the evolution characteristics of Irtysh River in Xinjiang were analyzed. The results show that the Irtysh River is a composite meander integrated by valley meander and free meander according to the geomorphic features formed by meandering. Judging from the characteristics of this river, the average slope of riverbeds is 0.5188 ‰; the average curvature is 1.72. By observing dry oxbow lake sites, right bank swung more violently than left bank in historical period. Since 1972, 23 reaches were cutoff; 15 reaches’ concave banks expanded; 55 tributaries broke away from the main riverway because of flow cutoff; 94 reaches moved to downstream. These changes increased sharply since 1997 after the construction of key water control project in the upstream of the Irtysh River.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
