Green Infrastructure and Ecological Technology Application Based on Lakes Overall Protection: A Case Study of Wolong Lake Area of Shengyang

This paper studied the green infrastructure and ecological technology application based on lakes overall protection, in the case of Wolong Lake area in Shenyang, Liaoning Province of China. Wolong Lake is located in boundary of Liaoning, Jilin and Inner Mongolia Province, and closed to Horqin sandy land. It is the second largest fresh water lake in northeast China, which is important node for eastern Asia bird migration and for migratory bird propagation in summer. It is the important ecological security strategy node in Liaoning Province and even in Northeast China for the ecological security effect of sand fixation, freshwater supply, birds conservation, etc. It has some practical significance for the study of lake and estuary landscape ecological planning in small town of Northeast China, especially for the the green infrastructure planning.

Increasing land utilization, population aggregation and strong land–sea interaction make coastal areas an ecologically fragile environment. The construction of an ecological security pattern is important for maintaining the function of the coastal ecosystem. This paper takes Jiaodong Peninsula in China, a hilly coastal area, as an example for evaluating landscape ecological risk within a comprehensive framework of “nature–neighborhood–landscape”, based on spatial principal component analysis, and it constructs the ecological security pattern based on the minimum cumulative resistance model (MCR). The results showed that the overall level of ecological risk in the study area was medium. The connectivity between the areas of low landscape ecological risk was relatively low, and the high risk areas were concentrated in the north of the Peninsula. A total of 11 key ecological corridors of three types (water, green space and road corridors) and 105 potential corridors were constructed. According to the ecological network pattern, landscape ecological optimization suggestions were proposed: key corridors in the north and south of Jiaodong Peninsula should be connected; urban development should consider current ecological sources and corridors to prevent landscape fragmentation; and the ecological roles of potential corridors should be strengthened. This paper can provide a theoretical and practical basis for ecological planning and urban master planning in coastal areas in the future.

The Green Infrastructure Strategy is used in different directions related to the design, protection and protection of the environment. Purpose. Analyze international experience in using the concept of green infrastructure, identify the main theoretical and practical approaches to assessing green infrastructure, analyze how to integrate green infrastructure strategies into territorial planning and integrate natural resources management in Europe and the world into policies. Methods. Literary search, analysis, synthesis, synthesis. Results. An analysis of scientific sources on the issue of studying the concept of green infrastructure; a review of the literature in related studies that directly or indirectly relate to the green infrastructure. It has been established that there are certain regional differences in the use of the concept of green infrastructure in Europe, America, and Asia. Directions of practical research in this area depend on the goals, functions and existing elements of the green infrastructure. As a result, its methodology can be modified. The possibilities and limitations of its use in Ukraine are revealed. The green infrastructure strategy has the greatest application in Europe and the USA to provide the ecological basis for the economic development of the territory. Now it is characterized as a development inward to greater detail, and in a spatial sense - covering all large areas. Conclusions. Given the lack of implementation mechanisms in Ukraine for the concept of green infrastructure, it is advisable to integrate it into landscape-ecological planning and recommend using it at the local level with subsequent spreading over large areas.

AbstractAnalyses of landscape change patterns that are based on elevation and slope can not only provide reasonable interpretations of landscape patterns but can also help to reveal evolutionary laws. However, landscape change patterns and their model in different landforms of the typical watershed in the Three Gorges Reservoir Area (TGRA) has not been quantified and assessed effectively. As a complex geographical unit, the ecological environment in the middle reach of the Yangtze River has experienced great changes due to the construction of the Three Gorges Project (TGP) and its associated human activities. Here, based mainly on a digital elevation model (DEM) and remotely sensed images from 1986, 2000, 2010, and 2017 and by using GIS technology, speeds/ trends of landscape change, the index of landscape type change intensity, landscape pattern indices, and landscape ecological security index, the spatial and temporal evolution characteristics of different elevations, slopes, and buffer landscape types were analyzed in typical watersheds, as well as an evolutionary model of the landscape pattern. The results indicated that (1) the landscape types along with the land classification and buffer zone that were influenced by the TGR construction have undergone a phased change, with the period 2000–2010 being the most dramatic period of landscape evolution during the impoundment period; (2) landscape type shifts from human-dominated farmland to nature-driven forestland and shrub-land as elevations, slopes and buffer distances increased. The landscape has shifted from diversity to relative homogeneity; (3) land types and buffer zones played essential roles in the landscape pattern index, which is reflected in the differences in landscape type indices for spatial extension and temporal characteristics. The results of this paper illustrate the spatial–temporal characteristics of various landscape types at three distinct stages in the construction of the TGR. These findings indicate that the landscape ecological security of the watershed is improving year by year. The follow-up development of the TGRA needs to consider the landscape change patterns of different landforms.
