چکیده
The study of ecological security patterns (ESPs) is great significance for improving the value ecosystem services and promoting both protection high-quality socio-economic development. As an important part “Loss Plateau-Sichuan-Yunnan Ecological Barrier” “Northern Sand Control Belt” in national strategic pattern, there urgent need to ESPs on Loess Plateau. Based a remote sensing dataset, this identified at different spatial scales, analyzed similarities differences sources, corridors, key points, so as better inform development implantation macro micro strategies. When taken whole unit, we 58 sources (areas with higher levels services) Plateau (total area 57,948.48 km2), along 134 corridors length 14,094.32 km), 1325 pinch points 315.01 2406 barrier 382.50 km2). splits into ecoregions, 108 67,892.51 226 13,403.49 2801 851.07 km2, 3657 800.70 Human activities land use types are main factors influencing number distribution points. constructed scales broadly similar, but significant among details were identified. such, when formulating restoration strategies, scale should be considered. Moreover, specific programs determined based ESP characteristics maximize biodiversity integrity from multiple perspectives directions.

Accuracy Assessment of Landform Classification Approaches on Different Spatial Scales for the Iranian Loess Plateau
An accurate geomorphometric description of the Iranian loess plateau landscape will further enhance our understanding of recent and past geomorphological processes in this strongly dissected landscape. Therefore, four different input datasets for four landform classification methods were used in order to derive the most accurate results in comparison to ground-truth data from a geomorphological...
متن کاملThe Loess Plateau
The Loess Plateau (34°–40°N, 103°–114°E) is situated in the northern part of Central China (Fig. 2.1). It borders on North China Plain in the east, adjoins Qinghai-Tibet Plateau in the west, stands in the north of Qinling Mountains, and neighbors Inner Mongolia Plateau in the north. The Loess Plateau is a part of the dryland region in northwest China, with its altitude in the range of 800–3000 ...
متن کاملChemical Organizations at Different Spatial Scales
The dynamics of spatial reaction systems that consists of many molecular species can be difficult to understand. Here we introduce a method that allows to observe the dynamics of a diverse spatial reaction system at different spatial scales. Using chemical organization theory we define for a given spatial location its so called spatial organization, which is the organization generated by the mo...
