Embodiment Construction

[0036] In order to describe the technical content and structural features of the present invention in detail, the following will be further described in conjunction with the embodiments and accompanying drawings.

[0037] Hainan Island is an important ecological conservation functional area in my country, and a good ecological environment is a prominent advantage in the construction of an international tourism island. With the advancement of the construction of an international tourist island, the pace of new-type industrialization and urbanization has accelerated, and human activities have had a great impact on the changes in the ecological environment of Hainan Island. Accurately and objectively analyze the impact of human activities on changes in the vegetation coverage of Hainan Island It can provide scientific data support for the rational planning and layout of relevant departments and the sustainable development of Hainan Island.

Abstract

The invention discloses a method of quickly evaluating the impact of human activities on the vegetation cover change. A long time sequence MOD13Q1 NDVI is taken as a data source. The data is analytically processed using MRT software to form an NDVI data set. The impact of human activities on the vegetation cover change is evaluated using a linear regression model, a least square trend analysis approach and a residual analysis approach. Through the method, large-scale research on the impact of human activities on the vegetation cover change can be conducted quickly, accurately and objectively based on long time sequence MOD13Q1 NDVI data and meteorological data. The potential of remote sensing satellite data and meteorological data in the large-scale evaluation of the impact on the ecological environmental is fully exploited.

Description

technical field [0001] The invention belongs to the field of environmental quality assessment, and relates to an environmental quality assessment method, in particular to a method for assessing the influence of human activities on vegetation coverage changes by using long-time sequence MODIS satellite remote sensing data and meteorological data. Background technique [0002] Vegetation is the main body of terrestrial ecosystems and an indicator of ecological environment monitoring. Changes in vegetation cover are driven by both climate and human activities. With the continuous acceleration of the urbanization process, the degree of influence of human activities on vegetation cover changes in local areas even exceeds that of climate change. Supported by data, it can also provide technical support for the sustainable development of regional economy and the construction of ecological environment. [0003] Most of the traditional research methods are field investigations and q...
