ESTIMATION OF GRASS YIELD IN LARGE REGION ON GEOGRAPHICALLY WEIGHTED REGRESSION MODEL
Geographically Weighted Regression (GWR) Model Grass Yield
2015/5/6
The grass yield embodies its productivity,and also is ground for developing animal husbandry production management. Now the remote sensing technology has been becoming an efficient and feasible mean...
A field experiment was conducted to study the effect of different crop sequences on water use, growth and yield of green gram (Vigna radiata (L) Wilezek) during 1992-93 and 1993-94 under r...
The groundwater table has been declining at a rate of 0.65 m/yr in Luancheng County since large scale groundwater extraction carried out in the 1960s. The drop of precipitation, substantia...
Abstract: This paper examines the experimental study on influence of material component to non-linear relation between sediment yield and drainage network development completed in the Lab....
Relationship between erosion and sediment yield in drainage basins of loess gully-hilly areas
2007/8/24
Abstract: From a long-term point of view, the balance between erosion and sediment yield in a drainage system can basically realize, i.e., the delivery ratio can be close to 1. However, substantial va...
