Embodiment

[0084] The analysis method of the present invention is explained in detail by taking the analysis of the vegetation cover change and the time lag effect of climatic factors in the Xijiang River Basin as an example, such as Figure 1-8 As shown, follow the steps below:

[0085] Step 1. Collect basic data first: 1> The NDVI data of the Xijiang River Basin has a spatial resolution of 500 m×500 m and an interval of 10 days from 2000 to 2013. It was obtained from the Geospatial Data Cloud Site of the Computer Network Information Center of the Chinese Academy of Sciences (http: / / www.gscloud.cn). ) Provide; 2> Xijiang River Basin and its adjacent areas Yuanjiang, Yuxi, Kunming, Huize, Zhanyi, Luxi, Mengzi, Pingbian, Panxian, Xingyi, Guangnan, Wangmo, Napo, Anshun, Qianxi, Bijie, Guiyang , Luodian, Fengshan, Baise, Jingxi, Longzhou, Pingguo, Dushan, Kaili, Hechi, Du'an, Sansui, Rongjiang, Nanning, Qinzhou, Fangcheng, Dongxing, Tongdao, Rong'an, Liuzhou Precipitation data of 51 meteorolo...

Abstract

The invention discloses a method for analyzing a regional vegetation coverage change and climate factor time lag effect. The method specifically comprises the following steps: collecting annual rainfall data, annual air temperature data and annual NDVI remote sensing data of a meteorological station in a research region; acquiring annual vegetation coverage time sequence raster data, annual rainfall capacity time sequence raster data and annual temperature time sequence raster data by calculations; respectively converting annual vegetation coverage, annual rainfall and annual temperature timesequence raster data into time sequence text form numerical data; and calculating the lag time limit of the vegetation coverage on the time lag effect of rainfall and air temperature, reaching the correlation when the lag time limit,achieving the lag time limit when the strongest time lag effect and the correlation when the strongest time lag effect. Tthe vegetation coverage change and the climatefactor time lag effect of the research area can be quickly and simply calculated by virtue of less data, and a scientific basis is provided for regional ecological construction decision making.

Description

Technical field [0001] The invention belongs to the technical field of regional vegetation coverage changes and climate response evaluation methods, and relates to a method for analyzing regional vegetation coverage changes and the time lag effect of climate factors. Background technique [0002] Since 1999, vegetation restoration projects have increased, and China's vegetation status has changed significantly. Vegetation is an important medium for energy exchange, water cycle, carbon cycle, and biogeochemical cycle of the surface ecosystem. Vegetation plays a very important role in maintaining regional climate stability. The study of vegetation dynamics has become one of the key issues in global ecological environment changes. One. Many studies have shown that there is a time lag effect between vegetation change and climate factors, that is, there is a time lag in the impact of climate factors on vegetation changes. Therefore, the study of vegetation cover change and its respo...
