“…For example, Wang et al (2006) used population density as a criterion to assess the impact human beings exerted on wetlands, but using population density cannot fully reflect information about artificial disturbances on wetlands. The influence gradient of human activities on natural ecosystems can be systemically evaluated using the LDI index (Chen and Lin 2013). Therefore, the methods proposed in this research can accurately assess the conversation effectiveness of WPAs.…”

The evaluation of conservation effectiveness for wetland protected areas (WPAs) is essential to underpin knowledge-based conservation policies and funding decisions by government and managers. In this paper, the conservation effectiveness for 28 WPAs in Northeast China from 2000 to 2012 was quantitatively evaluated using landsat thematic mapper image data and a maximum entropy model (Maxent). The spatial distribution of conservation effectiveness and the influence of human activities on conservation effectiveness were determined by combining a landscape development intensity (LDI) index and spatial analysis in a geographical information system. The results showed that the natural wetland area of all WPAs in Northeast China declined by 11.5 % and the conservation effectiveness of most of these WPAs decreased between 2000 and 2012. A significant negative correlation between the LDI index and conservation effectiveness (r = -0.824, p \ 0.01) suggested that human activities were responsible for the low conservation effectiveness of WPAs. The WPAs with the high conservation effectiveness were mainly located in the Da-Xing'an and Xiao-Xing'an Mountains, where anthropogenic activities were limited. The reduction in the conservation effectiveness of WPAs in the Songnen and Sanjiang Plains, which showed the most degradation, was due to conversion of wetlands to croplands. This research offers an efficient and effective method to evaluate the conservation effectiveness of WPAs. The results of this study will inform future ecological conservation and management of WPAs in China.

“…It has been directly used to evaluate the health of wetland ecosystem [44,49,50]. Some studies have developed the method by modifying the LDI coefficient and combining with other measure indexes, such as landscape matrix, forest cover, and road density to evaluate the current condition of wetlands [9,51,52].…”

Effects of Landscape Development Intensity on River Water Quality in Urbanized Areas

et al. 2019

Urban development and human activities have greatly changed the appearance of urban landscapes, and also affect urban river water environments. Rapidly urbanized regions in China face particularly severe pressures and challenges in alleviating degradation of river water quality. Information is needed on which indexes of landscape development intensity in rapidly-urbanized areas are the key factors affecting the quality of river water environments, and how these factors affect water quality. In order to answer these questions, this research selected six indexes belonging to three dimensions for landscape development intensity evaluation. Based on five water quality parameters of 20 rivers and the land use data of 20 small watersheds of Liangjiang New Area, Chongqing, China in 2014, this research explored the correlation between the landscape development intensity indexes and river water quality through redundancy analysis. We found that the impervious surface rate and the land average fixed asset investment are the key indexes to affect river water quality. Regulating the corresponding indexes at the urban planning and design level, as well as the decision making level, can effectively achieve the goal of improving urban river water quality. The conclusions inspire strategies in planning and design, and are helpful for government decision making to effectively protect river water environment in rapidly urbanized areas in the developing countries.

“…Area-Weighted Mean Patch Size (AREA_AM) is commonly used to compare alternative sites [53,113] based on the theory that bigger habitats are more valuable than smaller ones [93]. Landscape Shape Index (LSI), Total Edge (TE) and Edge Density (ED) are related to the edge effect in the field of landscape ecology [104,105,107,[113][114][115]. Total edge in class-level metrics is the most important index used in the study of fragmentation, and many of the class indices reflect the amount of class edge [91].…”

An Integrated Approach to Mitigation Wetland Site Selection: A Case Study in Gwacheon, Korea

et al. 2015

View full text Add to dashboard Cite

This paper presents an integrated approach to mitigation wetland site selection using functional landscape connectivity and landscape structure. This approach enables landscape designers to evaluate the relative priorities of mitigation wetland areas based on functional landscape connectivity and wildlife mobility, as well as landscape structure, composition, and configuration. The least-cost path method is used to evaluate candidate sites for mitigation wetlands with regard to wildlife movement. A set of assessments for landscape indices using FRAGSTATS was applied to identify suitable mitigation wetland areas on the basis of landscape connectivity, composition, and configuration. The study was conducted in Gwacheon, Korea, where there are plans for regional development that will change the landscape. In the first step, a group of 14 candidate sites is identified via analysis of functional landscape connectivity using the least-cost path method. In the second step, candidate mitigation wetland areas are ranked according to landscape connectivity and composition. The five mitigation wetland areas that were found to be suitable were analyzed based on landscape configuration at the class level. This study demonstrates OPEN ACCESSSustainability 2015, 7 3387 that functional landscape connectivity and landscape structure are important aspects to consider when identifying suitable sites for mitigation wetland planning and restoration.
