Abstract

The invention discloses a farmland straw resource spacial distribution estimation method. According to the method, a traditional statistical method is combined with the remote sensing technology, and statistical yearbook data and remote sensing net primary productivity (NPP) data are comprehensively utilized to conduct estimation on spatial distribution characteristics of farmland straw resources in the interior of a region. According to the farmland straw resource spacial distribution estimation method, the accuracy advantage of statistical data on the aspect of total amount calculation and advantages of remote sensing data on the aspect of reflecting the spatial distribution characteristics are fully utilized, and therefore the spatial distribution characteristics of farmland straw resources in the interior of the region can be reflected more accurately; on the whole, the farmland straw resource spacial distribution estimation method has the advantages of being rapid, simple, convenient and low in cost.
