市级国土空间规划核心指标纵向传导研究——以湖南省常德市为例

核心指标纵向层级传导作为市级国土空间规划的关键内容,对市域国土空间格局优化及规划统筹具有重要意义。针对当前指标传导研究不充分、不精细等问题,遵循“核心传导指标选择→指标传导技术逻辑构建→情景模拟预测”的研究思路,以常德市为例研究其2035年国土空间规划“市→县（区）”的核心指标传导。结果表明：（1）基于“指标全域总量预测—指标空间布局模拟—指标分区分类传导”的传导技术逻辑,通过SD与GeoSOS-FLUS模型的耦合集成利用,可有效实现市级国土空间规划核心指标“自上而下”与“自下而上”相结合的科学传导。（2）构建“人—地—业”协调的常德市国土空间利用SD模型,预测获得2035年市域核心指标总量,相应国土利用综合效益达12994.25亿元,相比2018年提升207.75%。（3）从指标传导结果来看,2035年常德市各县（市、区）社会经济类指标除常住人口规模指标外均保持增长趋势,边界类指标实现“只增不减”,用地类指标变化各异,但总体契合常德市主体功能区建设方向,核心指标传导结果符合实际。     

Virtual Garden Computer Program for use in Exploring the Elements of Biodiversity People Want in Cities

Urban ecology is emerging as an integrative science that explores the interactions of people and biodiversity in cities. Interdisciplinary research requires the creation of new tools that allow the investigation of relations between people and biodiversity. It has been established that access to green spaces or nature benefits city dwellers, but the role of species diversity in providing psychological benefits remains poorly studied. We developed a user‐friendly 3‐dimensional computer program (Virtual Garden [ www.tinyurl.com/3DVirtualGarden ]) that allows people to design their own public or private green spaces with 95 biotic and abiotic features. Virtual Garden allows researchers to explore what elements of biodiversity people would like to have in their nearby green spaces while accounting for other functions that people value in urban green spaces. In 2011, 732 participants used our Virtual Garden program to design their ideal small public garden. On average gardens contained 5 different animals, 8 flowers, and 5 woody plant species. Although the mathematical distribution of flower and woody plant richness (i.e., number of species per garden) appeared to be similar to what would be expected by random selection of features, 30% of participants did not place any animal species in their gardens. Among those who placed animals in their gardens, 94% selected colorful species (e.g., ladybug [Coccinella septempunctata], Great Tit [Parus major], and goldfish), 53% selected herptiles or large mammals, and 67% selected non‐native species. Older participants with a higher level of education and participants with a greater concern for nature designed gardens with relatively higher species richness and more native species. If cities are to be planned for the mutual benefit of people and biodiversity and to provide people meaningful experiences with urban nature, it is important to investigate people's relations with biodiversity further. Virtual Garden offers a standardized tool with which to explore these relations in different environments, cultures, and countries. It can also be used by stakeholders (e.g., city planners) to consider people's opinions of local design.

Abstract

The development of everthing follows its own law, which does not change at people's own sweet will. Therefore, we must study the development of things so as to grasp the essence of things in their deep meanings, explore the direction of their development, and make them better serve the people. As a part of the thought of sustainable development, city environment art will be of active significance to the perfection of the thought and will also be the concrete embodiment of the synthetic index of economic development. Such a thesis, starting from the macroscopic angle, and relying on the leading thought of sustainable development, takes hold of the development trend of city environment art, and explores the various problems that have arisen in city environment in the process of city management by combining thoughts on city planning, so as to guide urban harmonious development theoretically. The present paper expounds on the views comprehensively and, through the synthetic analysis on city planning, city environment, art esthetics and the thought of sustainable development, makes a detailed analysis of the effects of the present rapid city development on city environment.

Local economic development — the changing public/private sector relationship

The paper examines changing approaches to local economic development in the period since 1974. Initially, it proposes an ‘orthodox’ model of local economic development policies which emphasised the provision of a better industrial fabric, and of financial assistance to small, inner city firms. It suggests three recent directions of change in emphasis from this orthodox model: help in the creation of new entrepreneurs; replacement of public sector by private sector action; local authority shareholding in local firms by use of Enterprise Boards. Each approach makes different assumptions about the public/private sector relationship, the last two involve a more explicitly ideological stance on this issue.
