As a global event, urbanization will bring long-term effects to the supporting systems and ecosystem services of the whole world. The concept of Urban and Rural Non-construction Land (URNCL) is proposed based on ecological security. It is a spatial response to facing the grand challenge of resources and environmental and a demand to achieve sustainable development in rapid urbanizing regions. The paper carries out quantificationally and systematically comprehensive research of spatial evolution of URNCL and response of ecological security of Foshan city (ecological factor and ecosystem service) based on integrating multiple data sources including remote sensing data, land-use classification data, relevant statistical data and field survey and monitoring data and introducing remote sensing analysis methods, geographic information systems spatial analysis methods and mathematical model methods.

Carbon emissions caused by human activities are closely linked to the process of urbanization, urban land use and traffic system are two important factors that may influence it. On the basis of clarifying the space structure of low-carbon eco-city, this paper constructing an evaluation system of urban carbon emission from four dimensions: construction land compact, traffic carbon emission potential, road network accessibility, and public transportation accessibility. Based on the evaluation system, the author took the West New District of Jinan city as an example, evaluated urban planning scheme by using several spatial models such as landscape pattern index, Spatial syntax, POI (Point of Interest) kernel density analysis, and OD (Origin Destination) matrix in support of GIS (Geographic Information System) and RS (Remote Sensing) techniques.

In recent decades, China has experienced rapid urbanization; one way to expand an urban area is to construct new districts. The construction of new districts in China began in the 1990s with the "Development areas", which focused on industrial development and were the main mode at that time [1]. Since the 21 st century, "comprehensive new districts" have become important carriers of economic transition in many regions in China; industry development is no longer the primary purpose of the new districts, and attention has been paid to intensive land-use and ecological environmental protection [2]. The number of new districts in China has increased rapidly in the past

The cooling effect of green infrastructure (GI) is becoming a hot topic on mitigating the urban heat island (UHI) effect. Alterations to the green space are a viable solution for reducing land surface temperature (LST), yet few studies provide specific guidance for landscape planning adapted to the different regions. This paper proposed and defined the landscape complexity and the threshold value of cooling effect (TVoE). Results find that: (1) GI provides a better cooling effect in the densely built-up area than the green belt; (2) GI with a simple form, aggregated configuration, and low patch density had a better cooling intensity; (3) In the densely built-up area, TVoE of the forest area is 4.5 ha, while in the green belt, TVoE of the forest and grassland area is 9 ha and 2.25 ha. These conclusions will help the planners to reduce LST effectively, and employ environmentally sustainable planning.
