Abstract
The control of land development intensity is a prerequisite for urban construction and management, and rational intensity control is an inevitable demand and guarantee for urban scientific development. The study combines multi-source data information such as urban building information data, remote sensing aerial photography data, field survey data, urban planning data, questionnaire survey data, etc. On this basis, a Multi-dimensional model is established, and the development intensity model, technology, indicators, parameters, etc. are established. Explore and confirm. The article comprehensively considers the coordination between land potential and economic benefits, and environmental shaping, and conducts "value-based" control of the intensity of controlled planning and development. The results of the study show that the final land development intensity distribution of the Malong central urban area presents the highest land development intensity in the southwest and southeast of the old city. The final floor area ratio F of the lot is in the range of 1.4-2.2, showing a declining trend from the main lot to the peripheral lot.
Highlights
With the continuous development of urbanization, the transformation of old cities and the construction of new districts are advancing rapidly in many cities in my country
In the process of urban reconstruction and construction, the low land development intensity leads to the rapid expansion of urban land and the serious waste of land resources; too high land development intensity will bring about adverse effects such as the decline of urban environmental quality
The article emphasizes the influence of transportation factors on land development in the process of urban development, and analyzes the influence of transportation factors in depth through case comparison
Summary
With the continuous development of urbanization, the transformation of old cities and the construction of new districts are advancing rapidly in many cities in my country. In the process of urban reconstruction and construction, the low land development intensity leads to the rapid expansion of urban land and the serious waste of land resources; too high land development intensity will bring about adverse effects such as the decline of urban environmental quality. Whether it is predatory, extensive development or high-intensity, high-intensity development, it will affect the long-term sustainable development of the city. This article changes from a pure engineering perspective to a research perspective, based on urban and rural planning, geographic information systems, urban economics, urban sociology and other disciplines, starting from the driving force behind urban land use, revealing the various factors that affect the intensity of urban development, establish factor systems and models that affect the intensity of urban development and conduct empirical research
