※ brief introduction

Accumulated temperature is the sum of daily average temperature in a certain period , It studies plant growth 、 The requirement of heat for development and an index for evaluating heat resources , It is one of the important factors affecting plant growth , It is of great significance to guide agricultural production and ecological construction . As an important climate resource , The difference between accumulated temperature and other resources is that there are great regional differences and time changes . It is of great practical significance to understand the spatial variation and distribution of accumulated temperature .

※ Data information source

Annual average of meteorological stations ≥0℃ Annual accumulated temperature and place names of meteorological stations 、 longitude 、 Latitude and altitude data ; DEM data ; China border data .

※ Data interpolation algorithm

The spatial distribution of accumulated temperature and topography 、 Vegetation and other underlying surface characteristics are closely related , According to the idea of clustering , Cluster and partition the study area , Make the consistency of accumulated temperature distribution characteristics in the zone stronger . Then we use statistical method to find the law of annual accumulated temperature changing with altitude , To obtain high-precision estimation results .

Then, geographic location and terrain factors are introduced into the accumulated temperature interpolation , It well reflects the overall trend of the spatial distribution of accumulated temperature , It also shows the local subtle characteristics of accumulated temperature distribution , The overall accuracy of the accumulated temperature interpolation is improved .
