“…According to the "source-sink" theory, "source" landscapes are those that promote the development of ANPSP, while "sink" landscapes are those that prevent and delay the development of ANPSP [12]. The MCR model comprehensively considers the horizontal connections and ecological processes between landscapes by analyzing the resistance of matter and energy diffusing through landscape space from the source [13]. The "source-sink" landscape theory combined with the MCR model can help obtain an effective simulation of the actual situation, identify the transportation process of ANPSP, and evaluate critical spatial risks [14].…”

Agricultural non-point source pollution (ANPSP) is a primary cause of watershed water quality deterioration, and over 50% of NPS pollutants are estimated to come from ANPSP. Based on the “source-sink” theory and minimum cumulative resistance (MCR) model, ANPSP source and key resistance factors were integrated to identify areas at risk of ANPSP production and transportation into the waters of the upper Yangtze River basin. The results showed a spatial difference in the agricultural pollution sources of the basin, which were determined using both ANPSP loads and land-use types. Soil type, rainfall erosivity, and elevation were the three most important resistance factors in pollution transportation, weighting 0.373, 0.241, and 0.147, respectively. There was a spatial effect on the comprehensive resistance of ANPSP transportation, which was lower in mountainous terrain at the central basin. On the coupling of source and resistance processes, regions at serious risk of ANPSP were found to be concentrated in the southwest area. Areas at very high risk of NH3-N and TP pollution accounted for 37.6% and 38.1%, respectively, in the total town/street area. The spatial risk patterns identified in this study could be used for decision making and policy regulation of ANPSP and for aquatic environmental protection.

“…The minimum cumulative resistance (MCR) model can comprehensively consider the topography, geomorphology, environment and other influencing factors in the study area. It was first introduced by Yu Kongjian in China, and has been widely used in ecological corridor extraction by scholars at home and abroad in recent years [28][29]. The key to the application of the minimum cumulative resistance model is to set the landscape resistance surface.…”

Building an ecological security pattern is an important way to relieve ecological pressure and promote the harmonious development of human and ecosystem in the context of rapid urbanization. The article takes Qingdao, Shandong Province as the study area, and firstly identifies ecological sources by the Morphological Spatial Pattern Analysis (MSPA) method combined with the ecological red line of Qingdao City. Secondly, the potential ecological corridors are identified based on the Minimum Cumulative Resistance model (MCR) method, and the potential corridors are classified by gravity model. According to the research paradigm of "point-line-area", the ecological security pattern of "Four Zones, One Axis and One Belt" in Qingdao is constructed. The results show that the ecological security pattern of Qingdao consists of 22 ecological source areas, 128 ecological corridors and 16 stepping stones, with a total area of ecological source areas is 753.28 km 2 , mainly forest land and water, showing a spatial distribution pattern of "clustering from north to South and East and connecting in the middle"; the overall ecological network is well connected, but the spatial span between the north and south ecological source areas is large, and the construction cost of the ecological network is high; forest land and water are the main landscape types of the ecological corridor, and forest land has the largest area, accounting for 34.02% of the total area of the ecological corridor; in addition, arable land, as the main land for living and production, is seriously disturbed by man, accounting for 27.30% of the total area of the ecological corridor. Therefore, we should strengthen the ecological corridor protection and avoid excessive human interference with ecological sources, ecological corridors and stepping stones. As an important ecological barrier along the southeast coast of Shandong Peninsula, Qingdao takes its whole elements of ecological land as the life community, fully considers the ecological functions of ecological source areas and the spatial structure of ecological networks, and constructs the

“…The consistency of aesthetic preference judgment is affected by many factors, such as landscape quality, landscape type, and the mental image attained among recreational visitors [35,36]. At the same time, RL patterns play a key role in the play of the service value of RESs [37]; different landscape patterns will have an impact on the recreational experience of recreational users [38][39][40], and it can provide reference for decision makers in reasonably, sustainably planning for and developing potential recreation areas [41]. The Qinghai-Tibet Plateau is a worldclass leisure tourism attraction, with high-quality natural resources and a unique cultural landscape [42][43][44].…”

Recreational ecosystem services (RESs) are the subset of ecosystem services (ESs) that contribute to human society through recreation, recreation opportunities, and experiences. Existing RESs mostly focus on a single recreational landscape; alternatively, when mapping RESs, multiple types of landscapes are often drawn together, ignoring the differences in recreational landscape (RL) types and affecting the accuracy of the mapping. At the same time, quantifying the monetary value of RESs has been a challenge due to the lack of market substitutes that can approximate the prices associated with these non-excludable goods. This study used the MaxENT model, then classified and used recreational resource POI data, combined with environmental data on the existence or generation of different types of RL, mapped RES from the perspective of RL supply, and conducted monetization and evaluations of RL. The results show that the models’ AUC values are all greater than 0.7, and the distribution of RL supply can be drawn relatively accurately. The Qinghai–Tibet Plateau National Park Group (QTPNPG) has the largest high-quality geomorphic recreational landscape (69,081.02 km2), followed by a high-quality biological recreational landscape (59,348.65 km2) and a high-quality hydrological recreational landscape (33,251.20 km2). The national parks in the eastern part of the Qinghai–Tibet Plateau have a larger proportion of high-value areas of the RES. The total monetary value of the RES is CNY 8.323 billion, and the average monetary value of RES per unit area is CNY 20,200/km2. Our study optimizes the method of mapping RESs and provides a new way of quantifying the monetary value of RESs. The results can provide a reference for the recreational development of THE QTPNPG and its contribution to regional sustainable development.
