Most existing studies primarily examine the relationship between urban parks and individuals’ perceived restoration, with limited focus on the role of place attachment formed through interactions with urban parks. This research investigates the role of place attachment in the relationship between urban parks and young adults' perceived restoration. Using Zhongshan Park in Xiamen, China, as a case study, 312 valid questionnaires were collected and analyzed through a Structural Equation Model (SEM). The findings reveal that urban parks—categorized as natural elements, perceptual elements, rest elements, and activity elements—have a direct and significant positive influence on young adults' perceived restoration, with activity elements exhibiting the strongest effect. Additionally, most urban park elements significantly and positively impact place attachment, defined by place dependence and place identity. However, perceptual elements did not significantly influence place dependence, and rest elements did not significantly impact place identity. Notably, the study revealed that young adults' perceived restoration in urban parks can be indirectly influenced through two distinct pathways: place dependence and place identity. These insights provide a theoretical foundation for urban planners to design restorative parks effectively.

The contradiction between the demand of urban economic development and ecological environmental protection is becoming more and more prominent, and the reasonable construction of ecological corridors is of great significance for the protection of urban ecosystems. Taking Changle District of Fuzhou coastal city as an example, this study proposes an ecological source identification method from the perspective of “structure-function” by combining Morphological Spatial Pattern Analysis (MSPA) and Remote Sensing Ecological Index (RSEI) methods, and constructs and optimizes ecological corridors by means of the model of Minimum Cumulative Resistance (MCR) and Circuit Theory. The results show that: (1) a total of 20 ecological sources were extracted based on MSPA-RSEI; (2) a total of 31 ecological corridors were extracted based on Linkage Mapper, including 8 Level 1 corridors, 13 Level 2 corridors, and 10 Level 3 corridors; (3) the Pinch Point and Barrier Mapper software was utilized to identify 6.01 km2 and 2.59 km2, respectively, as Level 1 “pinch points” and barrier points within the study area. The land use types of these areas were as follows: The majority of “pinch points” were forested (60.72%), while the majority of barrier points were composed of construction land (55.27%), bare land (17.27%), and cultivated land (13.90%). (4) the optimal width of the corridor was determined by using the buffer zone method and gradient analysis: 30 m for the Level 1 corridor, 60 m for the Level 2 and Level 3 corridors, and the average current density before and after the construction of the eco-corridor was increased from 0.1881 to 0.4992. The results of the study can provide a reference for the decision-making of the ecological construction of the Changle District and the coastal urban areas of eastern China.

[目的]探究雨洪过程中不同降雨重现期下"源—汇"景观的时空动态演变特征,并生成雨洪灾害分布格局,从而为"源—汇"景观单元规划与区域雨洪灾害预防提供科学参考.[方法]以永春县景观因子指标数据为基础,引入可反映格局与过程关系的景观"源—汇"理论,基于最小累积阻力模型从景观因子阻力与径流动力平衡关系的角度重新划分"源""汇"景观.[结果]永春县初始"源"景观空间分布整体特征为"中部最高、西高东低",且集中在戴云山脉附近,易成为山体径流的源头.永春县在自然排水状态下,易转化为"源"景观的土地利用类型排序为:草地>耕地>建设用地>林地>未利用地.草地一直具有较强的"源"作用,耕地在降雨重现期大于10年后"源"作用增强,建设用地与林地在降雨重现期小于20年时吸收雨水的能力较好,超过20年后建设用地的"源"作用偏强,林地的"汇"作用偏强,未利用地的"源"作用几乎无变化,其吸收雨水的能力有待后续的验证.当降雨重现期为100年时,永春西北部雨洪灾害风险较大,高风险区多集中在一都镇、桂洋镇、东关镇,需重点防患.[结论]永春县雨洪灾害受到西北部山体径流影响,未来应从降低"源"景观、增加"汇"景观的角度深入研究.

The rapid increase in urbanization has brought about a great deal of ecological problems, and thus the systematic protection of the environment is vital. Ecological security patterns are important for maintaining regional ecological stability and sustainable urban development. Human disturbance is a key factor affecting the stability and sustainable development of ecosystems. This paper constructs an ecological security pattern and evaluates the degree of human disturbance in Fuzhou City. Through a comprehensive analysis of both of these factors, the ecological priority restoration areas in Fuzhou were identified. The study shows that (1) there are 40 ecological source areas in Fuzhou, with a total area of 4556.48 km(2); 83 ecological corridors, with a total distance of 179.33 km; and 30 ecological nodes. (2) The human disturbance degree score in the study area is between 0 and 0.8. The degree of human disturbance forms two larger major cores in Cangshan District, Gulou District, and Fuqing City. (3) The scores for the degree of human disturbance with ecological sources range from 0 to 0.42. The high-priority areas in the study area are distributed at the edges of ecological sources and form two high-scoring aggregation areas in Fuqing City and Jinan District. These corridors have a high degree of human disturbance with scores between 0 and 0.56. The I and II priority areas are mostly found in longer corridors in Fuqing City and Cangshan District near coastal or urban centers, and the III priority areas are mainly distributed in ecological corridors near the inland. The human disturbance degree scores of the nodes range from 0.01 to 0.27, and the nodes with higher grades were mainly distributed in the northeast, southeast, northwest and southwest of the study area.

Urban street greening is an important part of urban green infrastructure, and Green View Index (GVI) is widely used to assess urban street quality and ecosystem service value as an important indicator to quantify the perception of green street landscape from a pedestrian perspective. However, the distribution of street greenery is imbalanced. Therefore, to explore the differences in street greening levels within urban cities, we crawled streetscape data using the Internet to assess the spatial distribution patterns of urban street GVI using deep learning and spatial autocorrelation, and combined 11 surrounding environmental features with multi-source geographic data to further analyze the key factors influencing the spatial variation of block GVI using ordinary least squares, geographically weighted regression (GWR) models, and multi-scale geographically weighted regression (MGWR) models. The results show that the mean value of GVI in Fuzhou city is low (23.08%), with large differences among neighborhoods and a significant spatial autocorrelation. Among the regression models, MGWR has the best fit with an R2 of 0.702, where the variables of NDVI, house price, accessibility of water bodies and parks, and the proportion of built-up land have a greater impact on GVI, and the factors do not have the same spatial effect size. The results can provide a scientific basis for promoting green visual equity in different blocks.
