Ecological Vulnerability

Abstract Background Shennongjia is one of the most important ecological function areas and ecologically vulnerable zones in the world. With the rapid development of social economies, especially tourism, the ecological environment of Shennongjia has experienced profound changes. To describe an assessment method of ecological vulnerability, explain its application in Shennongjia, and propose optimization strategies to reduce the risk of ecosystem vulnerability and maintain regional ecological security and stability. Results (1) During the study period, the overall ecological vulnerability of Shennongjia is in a mild vulnerability level, exhibiting differentiation characteristics of high in the northeast and low in the southwest. High vulnerability zones are mainly distributed in the main towns and roads of Shennongjia. (2) The risk of ecological vulnerability of the entire region presents the characteristics of continuous decline. The ecological vulnerability composite index reaches the lowest value of 2.51 in 2018. (3) Land-use types, population density, and vegetation coverage are the main factors driving the evolution of ecological vulnerability. (4) A high level of coupling coordination exists between ecological vulnerability and landscape patterns, and the contribution of patch number and aggregation index to ecological vulnerability is substantial. Conclusions Analyses of the ecological vulnerability of Shennongjia shows that the entire region is in a mild vulnerability level. The extreme vulnerability risk of the northeast, south and southwest areas appears gradually, the vulnerability degree of the ecological environment shows polarization. The evolution of ecological environment in Shennongjia is the result of the interaction between human activities and natural environment. This study offers an effective way to assess ecological vulnerability and provides some strategies and guidance for improving ecological security.

Value Evaluation

The process of ecosystem service value evaluation has developed from the use of a single economic value that only accounts for material products to an assessment of ecological value and the value of ecosystem services. However, due to the complexity of ecosystems and different understandings of ecosystem service values, different classification methods of ecosystem services and service values have been developed internationally, and this has resulted in a lack of clarity regarding the correlation between ecosystem service value and various ecosystems. The correspondence between the system and each value type is not clear; therefore, based on an analysis of the inadequacy of domestic and foreign ecosystem service classification systems and methods, this study constructed a new accounting framework for non-monetary ecosystem service functions based on emergy analysis and integrated monetary accounting methods. The practical application of the method was also researched. The research results re-classified the value of ecosystem services, established an accounting method for various ecosystem service values, clarified the principle of addition in accounting, and avoided double counting. In the empirical analysis, a large number of correlation coefficients, parameters, and index values found in the foreign literature were used, so, our method also has value for international use.

Assessment of ecosystem services is vital for successful natural resource allocation; however, these have been less studied within Vietnam. This study estimated the ecosystem services value (ESV) and its change in Cham Chu nature reserve, Vietnam using a benefit transfer method. Ecosystem service values estimation and trend analyses were carried out based on land use and land cover datasets from 1986, 1998, 2007, and 2017, with their corresponding global value coefficients. The results revealed that the total value of ecosystem services in Cham Chu was approximately 64.4, 63.9, 60.7, and 63.4 million USD in 1986, 1998, 2007, and 2017, respectively. Changes have also occurred in the values of individual ecosystem service functions. From 1986 to 2017, ecosystem service functions showed significant decreases in gas regulation, pollination, biological control, water regulation, water supply, and food production of 62.9%, 51.2%, 44.4%, 24.7%, 23.1%, and 13.0%, respectively. We conclude that the loss of ESV is a result of ecological deterioration in the studied landscape, and we propose further research to examine future solutions and establish action strategies. In summary, the research approach methodology developed can be used by land managers and planners in Vietnam as a guideline to estimate the importance of ecosystem services in Vietnam.

Airborne Lidar Data

During the last decades the protection of nature has become a very important aspect due to the anthropogenic interference and structural alteration of the environment, especially in the peri-urban areas. Therefore, for a sustainable forest planning it is fundamental to get information about the actual state and the variation in landscape patterns concerning the forest layers. To this aim, an airborne laser scanning (LIDAR), a type of sensor which explicitly measures canopy height, was used to detect landscape patterns of broadleaf oak forest and for detecting the monumental trees in a peri-urban Natural Reserve: the Presidential Estate of Castelporziano (Rome).
