Study on the oasis corridor landscape in the arid regions based on RS and GIS methods—application of Jinta Oasis, China

The study on the oasis corridor landscape is a new hotspot in the ecological environment research in the arid regions. In oasis, main corridor landscape types include river, ditch, shelterbelt and road. This paper introduces the basic ecological effects of the corridor landscape on the transporting mass and energy and obstructing desert landscape expansion and incursion. Using Geographic Information System(GIS), we have researched the corridor distribution and its spatial relationship with other landscape types in the Jinta Oasis. Based on the dynamically monitoring on the landscape pattern change of the Jinta Oasis during the latter 10 years by using Remote Sensing(RS) and GIS,the driving functions of the corridors on this change have been analyzed in detail. The analysis results showed that all kinds of corridors' characteristics can be quantified by the indexes such as length and width, ratio of perimeter and area, density and non-heterogeneity. The total corridor length of Jinta Oasis is 1838.5 km and its density is 2.1 km/km 2. The corridor density of the irrigation land, forest and resident area is maximal, which shows that affection degree of the oasis corridors on them is the most. The improvement of the corridors quality is one of the important driving factors on the irrigation land and so on. The organic combination of the RS and GIS technologies and landscape research methods would be an effective means for the corridor landscape research on arid region oasis.

Ecological function regionalization of fluvial corridor landscapes and measures for ecological regeneration in the middle and lower reaches of the Tarim River, Xinjiang of China

The middle and lower reaches of the Tarim River are currently one of the main regions of ecological restoration in the arid areas of western China.Using the principles and method of landscape ecology,this study has chosen the fluvial corridor landscape in the middle and lower reaches of the Tarim River,and discusses the region’s ecologically functional regionalization system and issues related to its practical classification.On this basis the corresponding regionalizing principles and standards were developed which were used to qualitatively divide the three main landscapes as the ecologically functional areas in the drainage basin.The paper has also analyzed the characteristic of the study areas,and has put forward the measures for its ecological restoration.

Green corridor of rust belt: Theory and practice of organic growth in three-dimensional space of industrial heritage

This paper aims at the change of land use function in the development of urbanization and the planning transformation between the new and old cities.On the basis of protecting historical and cultural relics and improving environmental problems,new industries,new functions and new vitality are implanted,and a theoretical method of achieving economic,ecological and cultural symbiosis—the theory of organic growth in three-dimensional space is put forward.By analyzing the successful cases at home and abroad,this method summarizes the experience and lessons,and considers the various factors affecting humanity,region and sustainable development.This makes the cultural growth,ecological growth,business growth,to achieve a harmonious unity of the three.The feasibility and advanced nature of the theory to promote social development and optimize urban structure are demonstrated by combining with the reconstruction project of Hangzhou Steel Company(Hanggang)Ruins Park.
