Since EU Commission initiated Green Infrastructure (GI) strategy, an important step has been taken to help public to understand benefits of nature, such as providing food, clean air, and water resource. Besides, Green Infrastructure plays an important role in climate regulation, stormwater prevention, sustaining biodiversity. And its recreational function is also valuable for human society. Therefore, it is necessary to invest more resources in Green Infrastructure to develop, maintain and sustain it (Green Infrastructure COM, 2013).
Green Infrastructure is planned as a strategically network of natural and seminatural areas with environmental functions and its elements are designed and managed to deliver a wide range of ecosystem services it (European Environment Agency, 2011), which also provide solutions for urban and rural landscape conservation and sustainable development under the background of rapid and fundamental transformations in European landscapes.
Landscape corridor is identified as thin strips that connect isolated patches (Joshua J. T. et al., 2002). It has similar features such as connectivity, functionality, integration, and can be considered as a part of Green Infrastructure network from systems thinking, ecological thinking and social thinking. Landscape corridor can be defined as the linear landscape elements with cultural properties that represent the combined works of nature and of man. It is important due to its connectivity as well as its scenic, cultural, social, economical, ecological and recreational functions. Comparing with the concept of Green Infrastructure, we can find that Landscape corridor (LC) shares many common features with GI, but it also has its own properties gained from its unique linear form, such as connectivity and/or forming boundaries
