Abstract
Forest ecosystem is the most important terrestrial ecosystem type of species diversity in the world. The protection and sustainable use of forest ecological diversity is of great significance to forest protection and sustainable management. In order to maintain biodiversity, the traditional concept of forest resources management must be changed. In recent years, the mining and application of big data have become the frontier content of international ecological diversity and macroecology research. By establishing the discrete dynamic model of forest ecological diversity change, this study finds a method that can keep the number of trees stable in a short time and ensure the sustainable development of forest resources. This article studies and constructs the forest information system and constructs an open-source WebGIS (network geographic information system) scheme for the field of spatial information and supporting OGC (occupationally generated content). At the same time, the grey theory GM (1,1) model is used to predict the development trend of forest resources in China. The results show that under the promotion of policies and research projects, China’s forestry development has realized the double growth of forest area and volume, and the forest coverage rate has reached a new level.
Highlights
Ecological civilization is the main theme of today’s society, and it is a great progress in the form of human civilization and the concept, road, and mode of civilization development
Advocating ecological civilization has become an important guarantee for sustainable development in the new century
Studying the dynamic changes of forest resources, analyzing and mastering the laws of forest resources changes, and predicting its development trend can objectively and accurately evaluate the effect of forestry management and provide reliable and scientific arguments and basis for macro decision-making of forestry development
Summary
Ecological civilization is the main theme of today’s society, and it is a great progress in the form of human civilization and the concept, road, and mode of civilization development. Studying the dynamic changes of forest resources, analyzing and mastering the laws of forest resources changes, and predicting its development trend can objectively and accurately evaluate the effect of forestry management and provide reliable and scientific arguments and basis for macro decision-making of forestry development. En, how can we scientifically and Discrete Dynamics in Nature and Society rationally utilize and optimize the management of forest resources to ensure the sustainable development of the forestry and forestry economy? Many researches on forest ecological diversity change prediction are qualitative or simple quantitative models, without in-depth study of dynamic economic model explanation for sustainable development of forest resources, and it is far from enough to rely solely on these qualitative discussions or simple quantitative studies. It is necessary to conduct in-depth qualitative and quantitative research, dynamically analyze the harvesting of forest resources system, and benefit calculation, optimization, and decision-making of sustainable management schemes. It is necessary to conduct in-depth qualitative and quantitative research, dynamically analyze the harvesting of forest resources system, and benefit calculation, optimization, and decision-making of sustainable management schemes. eoretical derivation based on mathematical models is the most important work in theoretical methods [4, 5]
