Summary: | Land use and cover change is a leading edge topic in the current research
field of global environmental changes and case study of typical areas is an
important approach understanding global environmental changes. Taking the
Qiantang River (Zhejiang, China) as an example, this study explores
automatic classification of land use using remote sensing technology and
analyzes historical space–time change by remote sensing monitoring. This
study combines spectral angle mapping (SAM) with multi-source information
and creates a convenient and efficient high-precision land use computer
automatic classification method which meets the application requirements and
is suitable for complex landform of the studied area. This work analyzes the
histological space–time characteristics of land use and cover change in the
Qiantang River basin in 2001, 2007 and 2014, in order to (i) verify the
feasibility of studying land use change with remote sensing technology, (ii) accurately
understand the change of land use and cover as well as historical
space–time evolution trend, (iii) provide a realistic basis for the sustainable
development of the Qiantang River basin and (iv) provide a strong
information support and new research method for optimizing the Qiantang
River land use structure and achieving optimal allocation of land resources
and scientific management. |
