The Value Assessment of Ecosystem Service Function in Lingang Wetland Park

In this study, the ecosystem service function value of Lingang wetland park was calculated,such as hydrological regulation,water conservation and purification, biological habitat, erosion control, carbon sequestration and oxygen release port,with the market value method, carbon tax and forestation cost method, shadow engineering method, replacement cost method ,ecological value method and other methods. The results showed that the total ecosystem service function value of this wetland park is ¥1.03×108•a-1. The species habitat, carbon sequestration and oxygen release and hydrological adjusting function value is larger, which is 40.3%, 38.3% and 13.0% of the total value, so they are the main core function value of the Park. Therefore, the scientific and rational planning should be carried out in the development of the wetland park, avoiding influencing the ecosystem service function of this park.

Asset Value

In this study, we applied gross ecosystem product (GEP) theory in a case study to analyze and explain the natural resource asset value and ecosystem service value of forest resources in Jiaokou County, Shanxi Province, Northern China, in 2018. GEP refers to the total value of various final material products and services provided by ecosystems. In this paper, six service functions of a forest system, including water conservation, soil conservation, carbon fixation and oxygen release, forest nutrients, purification of atmospheric environment, and biodiversity, are valued by three calculation methods: the alternative cost method, market value method, and control cost method. The study revealed the following: (1) There is a parallel relationship between the value of natural resource assets and the value of ecosystem services. GEP includes the market value of natural resource assets, but it is mostly the value of ecosystem services. (2) The measurement of the physical quantity of forest ecosystem services depends on parameter data, and the monetary calculation often has no mature pricing basis, which leads to the large scale and uncertainty surrounding the evaluation results of ecosystem services. (3) The ecosystem service value and natural resource asset value have different practical significance, as well as alternate theoretical bases. The value of natural resource assets can be used as the asset valuation basis of economic transactions, which plays a role in macroeconomic management. The value of ecosystem services can be used as the basis of ecological compensation, providing information for the preparation of the balance sheet of natural resources.

Synergistic Relationships

Ecosystem services are characterized by region and scale, and contribute to human welfare. Taking Yantai city, a typical bay city in China, as the example, its three representative ecosystem services: food supply (FS), carbon sequestration (CS) and water yield (WY) were chosen as study targets. Based on analyzation of six different aspects of the supply and variation characteristic of demand, this study tried to propose advices for comprehensive improvement of ecosystem services for spatial optimization. The results showed that: (1) ecosystem services supply was strong in central and southern areas of Yantai, while the northern coastal areas were relatively weak; (2) synergistic relationships were found of FS-CS, FS-WY and CS-WY both in 2009 and 2015, with the strongest one for FS-WY. Additionally, in the synergistic relationships, each pair of ecosystem services was dominated by one ecosystem service; (3) most of the three pairs of synergistic relationships had the tendency to strengthen with larger scales; (4) four ecosystem demands changing areas were observed and comprehensive improvement suggestions for them were proposed. This work provides a new attempt to improve ecosystem services based on its supply-demand relationship, which will give a baseline reference for related studies in Yantai city, as well as other similar bay cities.

Abstract Key message A model for sustainable planning of urban tree stocks is proposed, incorporating growth, mortality, replacement rates and ecosystem service provision, providing a basis for planning of urban tree stocks. Abstract Many recent studies have improved the knowledge about urban trees, their structures, functions, and ecosystem services. We introduce a concept and model for the sustainable management of urban trees, analogous to the concept of sustainable forestry developed by Carl von Carlowitz and others. The main drivers of the model are species-specific tree diameter growth functions and mortality rates. Based on the initial tree stock and options for the annual replanting, the shift of the distribution of the number of trees per age class can be predicted with progressing time. Structural characteristics such as biomass and leaf area are derived from tree dimensions that can be related to functions such as carbon sequestration or cooling. To demonstrate the potential of the dynamic model, we first show how different initial stocks of trees can be quantitatively assessed by sustainability indicators compared to a target stock. Second, we derive proxy variables for ecosystem services (e.g. biomass for carbon sequestration, leaf area for deposition and shading) from a given distribution of the number of trees per age class. Third, we show by scenario analyses how selected ecosystem services and functions may be improved by combining complementary tree species. We exercise one aspect (cooling) of one ecosystem service (temperature mitigation) as an example. The approach integrates mosaic pieces of knowledge about urban trees, their structures, functions, and resulting ecosystem services. The presented model makes this knowledge available for a sustainable management of urban tree stocks. We discuss the potential and relevance of the developed concept and model for ecologically and economically sustainable planning and management, in view of progressing urbanization and environmental changes.

Abstract: Performance measurement in determining the Tax Object Acquisition Value as the basis for the imposition of duties onAcquisition of Land and Building Rights is conducted by analysis tool using assessment sales ratio (ASR). ASR analysis aims todetermine the level of conformity of Tax Object Acquisition Value (NPOP) to land market value to determine whether Tax ObjectAcquisition Value is in proportion, experienced under assessment, or over- assessment. Moreover, this technique also aims tomeasure diversity (variability) to account the level of fairness of Tax Object Acquisition Value as the bases of Duty on Acquisitionof Land and Building Rights (BPHTB). The results shows that the determination of Tax Object Acquisition Value as the bases todetermine BPHTB in Ambarketawang is lower compared to its property market value (under-assessment occurred). The variabilityon the determination of Tax Object Sales Value NPOP as the bases to determine BPHTB in Ambarketawang village is high, impliesthat it does not indicate good uniformity.Keywords: Tax Object Acquisition Value, Property Market Value, Assessment Sales RatioIntisari: Pengukuran kinerja dalam penetapan Nilai Perolehan Objek Pajak (NPOP) sebagai dasar pengenaan Bea Perolehan Hakatas Tanah dan Bangunan (BPHTB) dilakukan dengan alat analisis assessment sales ratio(ASR).

Carbon is crucial for life and exists in various reservoirs, such as plant tissues, soil organic matter, geology, and atmosphere. There is a direct relationship between carbon dioxide (CO2) levels in the atmosphere and rising temperatures. CO2 is removed from the atmosphere and stored in ecosystems. Carbon sequestration (CS) – the process of capturing and storing atmospheric CO2 – and expanding C storage of soils are appealing climate change (CC) responses. Agricultural soils are one of the largest C reservoirs and have potential for extended CS. Thus, protecting this ecosystem service (ES) we obtain from soils is crucial for addressing CC. Soil protection legislation should incorporate the significance of CS. The key issues in the sphere of natural resources can only be addressed by utilizing natural sciences in legal arguments. Accordingly, this study begins with highlighting the importance of soils for CS from a natural science perspective. This study analyses soil protection laws in the UK by scrutinizing whether they eliminate pressures on agricultural soils in a way that protect CS. The findings of this study suggest that soil protection laws do not offer a satisfactory protection for CS. We conclude by discussing alternative approaches for protecting CS in an effective manner and reverse the current trends in ES protection.
