Embodiment Construction

[0029] The specific implementation method of the present invention will be further described below through an application example of a method for quantifying the vegetation consumption of human activities on the Xilin Gol Grassland in my country's Inner Mongolia.

[0030] Implementing a method for quantifying vegetation depletion by human activities proceeds in the following steps:

[0031] Step 1. Collect the meteorological data of the stations in the study year in the study area

[0032] Collect the daily precipitation and daily average temperature of all meteorological stations in the study year for 365 days, sum the daily precipitation to obtain the annual precipitation of the meteorological stations, and perform arithmetic mean of the daily average temperature greater than 0 degrees Celsius and less than 30 degrees Celsius Calculate and obtain the annual average biological temperature of the meteorological station.

[0033] Step 2. Obtain the grid meteorological data of ...

Abstract

The invention discloses a method for quantizing vegetation consumption of human activities. The method comprises the following steps of collecting station meteorological data in a study region in a study year; obtaining grid meteorological data in the study region in the study year; obtaining a vegetation coverage diagram in the study region in the study year; computing vegetation potential productivity in the study region in the study year; obtaining MOD17A3 data in the study region in the study year; extracting vegetation actual productivity in the study region in the study year; computing the vegetation consumption of the human activity in the study region in the study year; and computing the vegetation consumption degree of the human activity in the study region in the study year. According to the method, the vegetation consumption time, the vegetation consumption place and the vegetation consumption degree of the human activity in the region can be given quantitatively, and the quick and accurate quantization of the vegetation consumption of the human activities can be realized.

Description

technical field [0001] The invention relates to a method for quantifying the consumption of vegetation by human activities, in particular to a method for quickly, efficiently, inexpensively and accurately quantifying the consumption of vegetation by human activities by using satellite remote sensing data and meteorological data. Background technique [0002] Terrestrial vegetation fixes atmospheric carbon dioxide in the form of carbohydrates in terrestrial ecosystems through photosynthesis. Vegetation productivity is the material carrier for terrestrial ecosystems to obtain energy and fix carbon dioxide. It is the main component of ecosystem carbon storage and plays a very important role in the formation of ecosystem structure and function. [0003] Climate change and human activities are the driving factors affecting terrestrial vegetation productivity. At present, human activities (such as grazing, felling, reclamation, etc.) have become the main factors in the change of ...
