A Study on Schematic Language of Cultivated Land Form in Linpan, Western Sichuan

Cultivated land is not only provided with the attribute of natural landscape, but also the carrier of means of production and social form. Some characteristic forms of cultivated land have become the common heritage of human cultural landscape. In recent years, with the change of land circulation and people's modes of production, the cultivated land form has gradually lost its original characteristic texture. Therefore, how to protect and extend the cultivated land form needs urgent attention and research. The survey selected the existing remote sensing image of Dujiang Dam by Local Space Viewer, interpreted and extracted the schema of cultivated land form in Dujiang Dam, drew the schematic language such as "characters", "words" and "phrases" according to its scale, and analysed its landscape ornamental value. Then, historical remote sensing was used to analyse the change of cultivated land form in Dujiang Dam, and field investigation and questionnaire distribution were combined to seek the cause and result of the change of cultivated land form. These provide support for future landscape aesthetics research.
