Abstract

The invention discloses a method and system for simulating a vegetation productivity spatial pattern based on climate and soil, and the method comprises the steps: screening climate factors limiting vegetation productivity, carrying out the linear standardization processing of the climate factors according to the tolerance of vegetation to climate limitation, and obtaining a climate variable simulating the vegetation productivity spatial pattern; selecting soil attributes influencing vegetation productivity as soil quality evaluation indexes, performing standardization processing, constructing soil quality parameters representing overall soil conditions of vegetation growth; and multiplying the standardized climate factor by the soil quality index to obtain a climate-soil index which is used for reflecting a vegetation productivity spatial pattern. According to the method, the technical scheme of simulating the vegetation productivity spatial pattern with more comprehensive consideration, higher interpretation degree and higher applicability is constructed, and the problems that an existing vegetation productivity model rarely considers soil factors, multiple input variables exist and calculation is complex can be solved.

Description

technical field [0001] The invention relates to the field of geospatial technology, in particular to a method and system for simulating the spatial pattern of vegetation productivity based on climate and soil. Background technique [0002] As a key component of the carbon cycle in terrestrial ecosystems, vegetation productivity plays a vital role in the process of carbon sequestration from the atmosphere to the biosphere. The large-scale spatial pattern of vegetation productivity is usually determined by environmental factors. In recent years, the simulation of regional and even global vegetation productivity has become an urgent issue to be solved. However, due to the huge workload of direct observation of sample points and the difficulties of deriving from the sample point scale to a larger scale, a large number of models have been proposed to estimate large-scale vegetation productivity. These models are currently divided into two categories: statistical models and proce...
