Moso bamboo forest ecosystem services value are divided into six groups: water storage, soil conservation, C fixation and O2 release, nutrients accumulation, environment purification, biodiversity conservation in this paper. Chinese Fir Plantation as the control was to compare. The results showed that: (1) The total value of Moso bamboo forest ecosystem services in Suichang County was 1260.40 million -1 yuan·a , services values of water storage, soil conservation, C fixation and O2 release, nutrients accumulation, environment purification, biodiversity conservation were respectively 741.00 million yuan·a-1,81.00 million yuan·a- 1,331.00 million yuan·a-1,21.6 million yuan·a-1,32.2 million yuan·a-1,53.6 million yuan·a-1. (2) The total value of Moso bamboo forest ecosystem services in Suichang County has increased 302.80 million yuan·a-1, the growth was about 31.62 percent. (3)In the six groups, all of Moso bamboo ecosystem services value more than the same area of Chinese Fir forest plantation. These provide a reference basis for the similar region to evaluate Moso bamboo ecosystem services value, demonstrating the important contribution of Moso bamboo to the forest ecosystem of Suichang County's sustainable development.

In order INTRODUCTION to get the total value of ecosystem services and survey for 6 ecosystem services value which one has The forest ecosystem service function refers to the the highest benefits in Suichang County. It provided a forest ecosystems and ecological processes that reference basis for the similar region to evaluate and formed and maintained by the natural environmental analysis Moso bamboo forest ecosystem services conditions and their effectiveness for human survival, value. and the forest ecological system has special ecological significance to maintain the natural MATERIALS AND METHODS ecological system pattern, function and process.

There is still a lack of dynamic ecological risk assessments for the corresponding classification-based prevention strategies and landscape ecosystem attributes’ enhancement. Based on the land-use changes, this study integrated the ecosystem structure and function to explore the characteristics of the landscape ecological risk in traditional village clustering areas. The clustering area of 24 national traditional villages in Songyang County of Lishui City in Zhejiang Province, China, served as the study region to evaluate and analyze the changes in the landscape ecological risk from 2010 to 2019. The results showed that the land-use transitions were subtle but dominated by changes from forest cultivated land, posing high risk and medium—high risk increased slowly in size. Additionally, significantly Citation: Liu, S.; Bai, M.; Yao, M. increased risks were located mainly in the boundary area of the five villages. Moreover, 22 settlements Integrating Ecosystem Function and were found in the sensitive area with increased risks less than 600 m away.

Using first-hand, village-level data from Zhejiang—an economically developed province in China—we investigated the patterns and influencing factors of population migration between rural and urban areas. We conceptualized three types of migration in rural areas: rural out-migration, rural in-migration, and rural return-migration. First-hand data were collected from 347 villages. The results show that although rural out-migration remains the dominant form of migration, rural in- migration and return-migration are also common, and the latter two are positively correlated. Further, we found evidence to support the conclusion that rural economic, social, and spatial development encourages rural in-migration and return-migration but does not have a significant impact on rural out-migration. Therefore, it is foreseeable that rural in-migration and return-migration will become increasingly common in China. Citation: Tong, W.; Lo, K.

Nevertheless, hydrodynamic pressure is rarely considered in the traditional limit equilibrium slice method of slope stability analysis since effective and reliable hydrodynamic pressure data are often lacking in practice. Moreover, efficient methods to involve these data in slope stability analysis are an urgent need. To overcome these concerns, the flow velocity and direction system (FVDS) is employed to measure the groundwater flow velocity, which can be used to generate hydrodynamic pressure samples at different monitoring points. Based on these samples, the hydrodynamic pressure of each soil strip is estimated using artificial neural networks (ANNs). Afterward, an improved Bishop method that considers hydrodynamic pressure is proposed. The effectiveness and significance of the proposed method are illustrated with a case Citation: Ge, Q.; Zhang, J.; Chen, Z.; study, the Fanshantou landslide in Zhejiang Province, China. The safety factor before and after taking Li, J. Application of Flow Velocity and drainage countermeasures is also calculated and compared.

Ltd, Hangzhou, China 3Zhejiang Electric power construction Co. Ltd, Ningbo, China Submitted 23 January 2017; resubmitted 13 April 2017; accepted 20 April 2017 Abstract. At the phase of 13-th five-year plan in China, natural gas will play an important role in energy revolution. With the growth of consumption, natural gas infrastructures will become hot spots of future investment and pipeline network construction will also usher in a period of rapid development. Therefore, it is of great theoretical and practical significance to study layout methods of transport pipeline network. This paper takes natural gas transport pipeline net- work as a research object, introduces dominance degree to analyse benefits of pipeline projects. Then, this paper pro- poses Dominance Degree Model (DDM) of transport pipeline projects based on Potential Model (PM) and Economic Potential Theory (EPT). According to DDM of gas transport pipeline projects, layout methods of pipeline network are put forward, which is simple and easy to obtain the overall optimal solution and ensure maximum comprehensive benefits. What’s more, construction sequences of gas transport pipeline projects can be also determined. Finally, the model is applied to a real case of natural gas transport pipeline projects in Zhejiang Province, China.
