Urbanization is the development trend of all countries in world, but it has caused considerable ecological problems that need to be alleviated by building security patterns. This study took Ningbo as an example construct and optimize pattern. We analyzed land use types, normalized difference vegetation index, landscape connectivity for sources selection. In constructing resistance surface, we considered natural socio-economic factors. On this basis, identified corridors based on a minimum cumulative model. Finally, pattern was optimized through space syntax. Results showed 18 sources, with area 3051.27 km2 29 corridors, length 1172.18 km. Among them, 11 are first-level, 10 second-level, 8 third-level corridors. After optimization, protection cost were significantly reduced, which can effectively alleviate trade-off between economic development. research provide reference construction optimization patterns significance rapidly urbanized areas.

Ecological network is an important landscape approach for biodiversity and ecosystem conservation. However, the lack of further spatial analysis ecological zoning makes it difficult to implement conservation restoration measures based on network. In this study, we proposed a framework with case study in Yunnan Province, China. The results showed that area was consisted sources total 136496.56 km2, 276 corridors average length 41.40 km, pinchpoints barriers 425.54 km2 1422.83 respectively. Province divided into five zones Source protection zone included 153 watersheds, large high connectivity sources, needing conserve original natural ecosystem. enhancement 103 watersheds small discrete distribution. particularly southeast karst regions. Corridor construction 143 build dense orderly manner. node 15 watersheds. Key nodes needed enhance overall connectivity. Non-ecological be paid attention local can help light conditions.

Abstract Since the implementation of Chinese economic reforms. The habitat quality coastal has gradually deteriorated with development, but concept "ecological construction" slowed negative trend. For quantitative analysis correlation between Pearl River Delta urban expansion and changes in under influence policy, we first analyzed change based on InVEST model then measured impact construction land through index (HQCI) contribution (CI) indicators. Finally, urbanization level was evaluated using geographically weighted regression (GWR) Self-organizing feature mapping neural network (SOFM). results indicated that: (1) during study period from 2000 to 2020, declined due sprawl, indicating a deterioration ecological structure function, decrease most significant 2010. (2) had effect quality, have improved after 2000, reflecting positive policies such as civilization (3) degree varies greatly among cities area: Shenzhen, Dongguan, Foshan, Zhongshan best green development. These reflect role prevention damage caused by development provide reference for formulation sustainable spatial differences.

Carbon neutrality, achieved by increasing carbon sinks, is an effective strategy for solving the increasingly serious global climate change problem. The continuous exploitation of resources has damaged, original ecosystem mining cities leading to poor vegetation growth environment and decreased regional sink capacity. Therefore, it crucial restore enhance ecological region strengthen capacity vegetation. However, studies on spatial network optimization are few. Here, we constructed Xuzhou City, a city in China, using modified minimal cumulative resistance model (MCR). Subsequently, calculated topological properties nodes City combining complex theory with proposed scheme optimize landscape space based conditions. functionality sources was determined coupling results Functional description Remote Sensing Index (RSEI) integral index connectivity (dIIC). sinks were estimated land use indicators correlated sinks. showed significant positive correlation betweenness centricity. We accordance sources. Finally, effect robustness sink. stability optimized restoration significantly improved, while simultaneously enhanced. Through national construction projects, renewal can effectively cities, thus achieve goal neutrality. This study provides theoretical measure reference future engineering cities. Additionally, also be applied remote sensing promote urban development sustainability.

The expansion of human activities has significantly increased ecological risks, which threaten the security ecosystems. This paper takes Northeast China, a national typical barrier region, as case study to explore evolution environment under various future development scenarios. Considering complexity assessments, comprehensive approach integrating methods is employed. includes Patch-based Land Use Simulation (PLUS) model, Integrated Valuation Ecosystem Services and Trade-offs (InVEST) landscape risk assessment index system, Space Minimum Cumulative Resistance (MCR) among others. These are used dynamically assess changes in land use, (LER), layout networks. An integrated framework proposed for identifying, constructing, optimizing network (ESN). results show that LER China presents "high middle, low around" distribution characteristic.
