The rapid economic growth after the new millennium could be characterized by the reappearance of heavy industrialization and land urbanization. In the literatures, extensive studies have examined the impact of energy and emissions on the growth quality during the heavy industrialization process, but few have paid attention to the land dimension. This paper aims at studying the role of land use ...
Soil erosion and sediment yield from watersheds confine sustainable use of land resources and is supposed as one of the most critical environmental issues. Prediction of storm wise soil erosion and sediment yield is very important, especially in arid and semiarid regions due to small number of events and high intensity of rainfall. Evaluation of soil erosion by existing models is needed as an i...
This article aims to build a set of exploratory and strong operability evaluation index system, the collection of 3 cities in zhengzhou to use construction land on the basis of economic efficiency index of related data, the selection of the zhengzhou region as the object of empirical study, using data envelopment analysis (DEA) method), and C squared R dual model, with the help of a DEAP Versio...
Introduction: Land use mixing is one of the essential components of the urban landscape in the sustainable development of urban areas and diversity of land uses. The location of urban land-uses has a significant impact on the quality of life and efficiency of services related to different land uses. Mixed land use enables residential, work, shopping, and public services adjacent to each other a...
