Abstract

The invention relates to a land utilization / covering information space-time monitoring method and technology based on priori knowledge. The land utilization / covering information space-time monitoring method comprises the following specific steps: performing geometric registration on multi-source land utilization / covering data; performing scale conversion of multi-source land utilization / covering data; carrying out data conversion on the multi-source land utilization / covering data; performing priori knowledge extraction based on multi-source land utilization / covering; performing land utilization / covering information extraction based on priori knowledge; carrying out long-time sequence land utilization / covering space monitoring; and carrying out space-time simulation and prediction on land utilization / covering information. The method has the advantages that: 1), existing land utilization / covering products and achievements at home and abroad are mined and utilized, and rapid extraction of land utilization / covering information is effectively achieved; 2) simulation and prediction of land utilization / covering are effectively realized, technical support is provided for scientific monitoring and space cognition, and 3) an evaluation method and decision support are provided for global town planning, living environment quality monitoring and ecological environment protection.

Description

technical field

[0001] The invention relates to a method for temporal and spatial monitoring of land use / cover information based on prior knowledge, and belongs to the technical field of environmental monitoring and protection. Background technique

[0002] Land Use / Land Cover Change (Land Use / Cover Change, LUCC) truly reproduces the spatiotemporal dynamic change process of the surface landscape, and is the most intuitive manifestation of the interaction between human socioeconomic activities and the natural environment. Its spatial pattern represents the human-human The intensity and mode of action of land relations on different spatial and temporal scales reflect changes in the structure, pattern, and function of the ecological environment, and affect the threshold value of the ecological environment and the output type of service functions. Land use / cover plays a decisive role in maintaining ecosystem service functions. It objectively records the change process of the spa...
