Research on design method for the blue-green ecological network system to deal with urban flooding: A case study of Charleston Peninsula

Abstract

1 key laboratory of urban agriculture in central china, ministry of agriculture and Rural affairs, huazhong agricultural university, china. 2 clemson university, united States of america.aBSTRacT The landscape strategy to deal with climate change has become an important issue in the process of sustainable urban development in the world. Particular focus is given to the charleston Peninsula in South carolina, uSa, which faces floods due to inefficiency in stormwater collection systems, increased frequency of intense rain events, excessive impervious surfaces, tide cycles, etc. In addition, hurricane events and sea-level rise are considered sources of flood risk in the coastal areas of the peninsula. This research draws on existing urban stormwater management theory to argue that the blue and green water ecological network system in the built-up area represents an innovative approach to alleviate flooding and promote a healthy landscape during urban renewal. according to the analysis of hydrological characteristics, the peninsula is divided into 17 basins, and then each basin is studied separately. Within Basin 8, the potential block is divided into four types of functional stormwater management units (fast flow zone, absorption containment zone, additional digestion zone, and upstream interception zone) and connected by a reintegrated drainage system. finally, the corresponding micro-landscape strategy is proposed according to the block property. functional units simultaneously undertake the functions of rainwater management and landscape activities. In the end, the new active-recreation space and passive-recreation space in the network are connected with the original urban green space and provide the city with a series of unique ecosystem services to support urban drainage systems and human health. It is hoped this research will provide an attempt for future urban stormwater management from the perspective of landscape planning and design.

Incentives for Green and Low-Carbon Technological Innovation of Enterprises Under Environmental Regulation: From the Perspective of Evolutionary Game

“…However, there is still no consensus on the direction of the impact of government environmental regulations on green and low-carbon technological innovation of enterprises. Many scholars believe that the adoption of environmental regulation means by the government can effectively encourage enterprises to conduct green and low-carbon technological innovation (Brunnermeier and Cohen, 2003;Lin and Yang, 2011;Dietrich and Chen, 2018;Liang et al, 2019). Some scholars, such as supporters of the Porter Hypothesis, believe that environmental regulation measures have to some extent inhibited enterprises' green and low-carbon technological innovation behavior (Chintrakarn, 2008).…”

Integrated spatial regulation strategy of blue-green body space for urban ecological restoration

“…With the acceleration of urbanisation, urban ecosystems are facing unprecedented pressure and challenges [1]. Over-exploitation, pollution and destruction in the process of urbanisation have led to the disruption of the balance of urban ecosystems, the decline of environmental quality, the reduction of biodiversity, and the increasing severity of climate change [2][3]. In order to maintain the ecological balance and sustainable development of cities, ecological restoration has become one of the important tasks in urban planning and construction.…”
