The rapid urbanization process, accompanied by the transformation of high-intensive land development and land use, constantly encroaches on habitat patches, making them increasingly fragmented and isolated, which directly influences the regional landscape pattern and sustainable development. Taking the Tomur World Natural Heritage region as the study area, the morphological spatial pattern analysis (MSPA) method and landscape index method were used to extract the ecological source areas of great significance to the construction of ecological corridors. Then, using the minimum cumulative resistance model (MCR), the comprehensive resistance surface was constructed and the potential corridors were generated by the minimum cost path method. Finally, according to the gravity model, the important corridors of the study area were designed. Results showed that the MSPA method and MCR model can be used in combination to identify the potential ecological corridors in the study area and clarify the priority of landscape element protection in the study area, which can provide guidance to construct the ecological network and provide reference for other regions as well.

Abstract Background With the increasing fragmentation of landscape induced by rapid urbanization, the construction of ecological networks is of great significance to alleviate the degradation of urban habitats and protect natural environments. However, there is considerable uncertainty when constructing ecological networks, especially the different approaches to selecting ecological sources. We used the southern Chinese city of Shenzhen as a study area to construct and optimize ecological networks using a coupling approach. Ecological source areas were extracted using morphological spatial pattern analysis (MSPA) and the landscape index method. Ecological networks were constructed using the minimal cumulative resistance (MCR) model and the gravity model. Stepping stones and ecological fault points were added in corridors to optimize the ecological network. Results Ten core areas with maximum importance patch values were extracted by the landscape index method as ecological source areas according to MSPA, after which corridors between ecological sources were constructed based on the MCR model. The constructed ecological networks were optimized using 35 stepping stones and 17 ecological fault points. The optimized ecological networks included 11 important corridors, 34 general corridors, and seven potential corridors. The results of corridor landscape-type analysis showed that a suitable ecological corridor is 60 to 200 m wide. Conclusions Overall, our results imply that ecological source areas can be identified virtually, and that ecological networks can be significantly optimized by combining MSPA and MCR models. These results provide a methodological reference for constructing ecological networks, and they will be useful for urban planning and biodiversity protection in Shenzhen and other similar regions around the world.

Urban agglomerations have become a new geographical unit in China, breaking the administrative fortresses between cities, which means that the population and economic activities between cities will become more intensive in the future. Constructing and optimizing the ecological security pattern of urban agglomerations is important for promoting harmonious social-economic development and ecological protection. Using the Harbin-Changchun urban agglomeration as a case study, we have identified ecological sources based on the evaluation of ecosystem functions. Based on the resistance surface modified by nighttime light (NTL) data, the potential ecological corridors were identified using the least-cost path method, and key ecological corridors were extracted using the gravity model. By combining 15 ecological sources, 119 corridors, 3 buffer zones, and 77 ecological nodes, the ecological security pattern (ESP) was constructed. The main land-use types composed of ecological sources and corridors are forest land, cultivated land, grassland, and water areas. Some ecological sources are occupied by construction, while unused land has the potential for ecological development. The ecological corridors in the central region are distributed circularly and extend to southeast side in the form of tree branches with the Songhua River as the central axis. Finally, this study proposes an optimizing pattern with "four belts, four zones, one axis, nine corridors, ten clusters and multi-centers" to provide decision makers with spatial strategies with respect to the conflicts between urban development and ecological protection during rapid urbanization.

Abstract Makino, M., and Sakurai, Y. 2012. Adaptation to climate-change effects on fisheries in the Shiretoko World Natural Heritage area, Japan. – ICES Journal of Marine Science, 69: . In the Shiretoko World Natural Heritage area, many factors have been observed that imply effects of climate change on ecosystems, such as decreases in seasonal sea ice, changes in fishing grounds, and the appearance of non-local species. This study summarizes observed and anticipated effects of such climate change on fisheries in the heritage area and discusses policy and research needs for adapting to these changes. International research and monitoring at the scale of large marine ecosystems (LMEs) is the basis of all policy measures for adapting to climate change. Several measures need to be combined, taking into account the various socio-ecological aspects of fisheries and scales of ecosystems. Such measures of adaptation should be incorporated also into the cross-sector coordination system and the Integrated Management Plan, which were established to manage the World Heritage area. Also, culture is an important part of society, and the World Heritage programme may offer clues for creating a new and peaceful culture based on the LME.

Monitoring the ecosystem health for world natural heritage sites is essential for protecting them and benefits the formulation of more targeted protection policies. This study used Bayanbulak world natural heritage site as a case, established a framework for assessing the ecosystem health through remote sensing based on the parameters of ecosystem vigour, organization, resilience, and services. Then, we verified the obtained results through field sampling. The results show that the ecosystem health in the overall study area had declined over time, however, the health within the property zone remained at high levels and stable. The area proportion of low health was low and primarily distributed in the buffer zone. Thus, in general, the ecosystem in the study area was healthy. Besides, the ecosystem health exhibited distinct spatial agglomeration characteristics, and the degree of agglomeration enhanced over time. In addition, the field vegetation samplings were consistent with the changes in the ecosystem health levels, therefore, the result of RS monitoring of ecosystem health were credible. Thus, this study provides a scientific basis for heritage managers to formulate suitable ecological protection policies and should aid further research on the ecological monitoring of heritage sites.
