舟山桃花岛桃花湾景观旅游规划探析

近些年大量游客涌入以及由此引出的各种服务设施建设造成了风景区自然景观严重的破坏，使风景区内原定的自然审美功能严重丧失。以浙江舟山群岛桃花岛桃花湾景观旅游规划为例，探析风景区规划新思路。在对舟山桃花湾现状和景观资源进行的科学分析基础上，规划着重探讨了旅游度假风景区的规划布局以及沿海沙滩景观的保护和利用，力求达到规划的生态效益、经济效益、人文效益和社会效益的统一。     

对风景名胜区规划中有关分区问题的讨论

分区是实施规划管理目标的基本工具和手段。与国外国家公园分区制相比,我国风景名胜区规划编制中存在着多种分区类型,并且对各类分区缺乏明确统一的规定,分区之间缺乏有效衔接,不仅影响到规划编制和管理实效,也将影响到国家对风景名胜区管理的统一性。通过分析当前风景名胜区规划编制在分区上存在的问题,探讨了各种分区的概念及其相互关系,重点建立了适应我国风景名胜区特点的功能分区模式,并提出需要进一步研究的3个问题：风景区评价技术、核心景区划定、分区与土地利用。     

黄山风景名胜区分区规划研究

分区规划作为协调保护和利用关系的重要手段,是风景名胜区总体规划中的核心内容。以黄山风景名胜区为例,介绍了现状多种分区并存的局面和分区之间的结构,分析了现状分区规划及其实施中存在的问题,再从分区类型、管理政策等方面提出规划改进意见,包括将分区细分为四大类十小类,以及针对具体的人类活动、人工设施和土地利用类型分别制定管理政策,最后提出分区监测的概念,并对监测指标和标准的选择进行了初步探讨。     

Modeling and solving mixed-model assembly line balancing problem with setups. Part I: A mixed integer linear programming model

This paper is the first one of the two papers entitled “modeling and solving mixed-model assembly line balancing problem with setups”, which has the aim of developing the mathematical programming formulation of the problem and solving it with a hybrid meta-heuristic approach. In this current part, a mixed-integer linear mathematical programming (MILP) model for mixed-model assembly line balancing problem with setups is developed. The proposed MILP model considers some particular features of the real world problems such as parallel workstations, zoning constraints, and sequence dependent setup times between tasks, which is an actual framework in assembly line balancing problems. The main endeavor of Part-I is to formulate the sequence dependent setup times between tasks in type-I mixed-model assembly line balancing problem. The proposed model considers the setups between the tasks of the same model and the setups because of the model switches in any workstation. The capability of our MILP is tested through a set of computational experiments. Part-II tackles the problem with a multiple colony hybrid bees algorithm. A set of computational experiments is also carried out for the proposed approach in Part-II.     

美国三座城市的设计审查制度比较研究——波特兰、西雅图、旧金山

设计审查制度是美国城市开发控制体系中针对城市形态、环境质量等城市设计问题的控制政策。设计审查以区划法为法律平台，以设计导则为评判依据。本文以波特兰、西雅图，旧金山三座城市的设计审查制度为例，对三座城市的设计审查制度的程序、参与人员、决策过程、审查标准等方面的基本情况进行了比较研究。     

Architecture of underground spaces: From isolated innovations to connected urbanism

This article provides an introduction to an architectural approach of subterranean space, presenting its properties and principles of development. It then analyzes some subsurface experiences of the 20th century and, by looking at their successes and failures, shows how a renewed human and dynamic vision could help move from developing isolated structures towards a connected form of urbanism. Such a transition would provide an adequate response to the challenges of modern metropolises, for instance in the Paris area. On the strength of these realizations, a national transdisciplinary research program was deemed necessary and this is how Ville 10D – Ville d’Idées came to be in 2013. This article thus recaps the history and reflection that led to the creation of the Ville 10D project, and explains how it emerged as a systemic approach to subterranean development.MethodConception and development of a change of paradigm: consider the living and motion as primary, unifying agents between the underground and the city above it; play with and act on the subsurface in order to reinject mixed uses and complexity into the city through a systemic approach of the underground in the urban eco-system.Creation of a research project whose organization reflects these concerns: in order to take the living into account, make the study as cross-disciplinary as possible, mixing competences and points of views.Four-fold organization – socio-economical, environmental, psycho-social, cognitive (knowledge and management of the underground) – corresponding to four main themes plus two transversal themes (legal and urban planning). Unfolding in four stages of 18 months each, these thematic approaches are casting converging light onto token sites chosen for their diverse typology. Around a hundred professional players are involved in the Ville 10D project.Study resultsBeyond the data gradually obtained through the project studies themselves, and without anticipating those to come, the first results so far have shown a growing awareness of and interest in the reality of underground potential. There has been a genuine gradual involvement of the development players, researchers and academics in elaborating the project.For us, gaining support from the players is an essential stake to “unlock” the underground in the minds first, then in reality thanks to tools built by Ville 10D in all the fields of development.ConclusionResearch reports are issued upon completion of each of the stages and posted on the website http://www.ville10d.fr. We are planning to present and publish the final reports at an international colloquium in 2017.

Quick energy prediction and comparison of options at the early design stage

The energy-efficient building design requires building performance simulation (BPS) to compare multiple design options for their energy performance. However, at the early stage, BPS is often ignored, due to uncertainty, lack of details, and computational time. This article studies probabilistic and deterministic approaches to treat uncertainty; detailed and simplified zoning for creating zones; and dynamic simulation and machine learning for making energy predictions. A state-of-the-art approach, such as dynamic simulation, provide a reliable estimate of energy demand, but computationally expensive. Reducing computational time requires the use of an alternative approach, such as a machine learning (ML) model. However, an alternative approach will cause a prediction gap, and its effect on comparing options needs to be investigated. A plugin for Building information modelling (BIM) modelling tool has been developed to perform BPS using various approaches. These approaches have been tested for an office building with five design options. A method using the probabilistic approach to treat uncertainty, detailed zoning to create zones, and EnergyPlus to predict energy is treated as the reference method. The deterministic or ML approach has a small prediction gap, and the comparison results are similar to the reference method. The simplified model approach has a large prediction gap and only makes only 40% comparison results are similar to the reference method. These findings are useful to develop a BIM integrated tool to compare options at the early design stage and ascertain which approach should be adopted in a time-constraint situation.
