“…3). Ecosystem service flows can be based on pre-existing corridors and networks in the landscape (Shen et al 2014). Bagstad et al (2014) showed that these flows were generated by source regions and depleted or blocked by sinks and rival uses, but not by non-rival use.…”

Purpose Ongoing population growth and economic development place increasing demands on the supply of services produced in and by ecosystems. The resulting degradation compromises their ability to continue supporting the provision of these services. As ecosystem services (ESs) are closely related to land use changes, studies linking these topics are critical in the context of better land use planning and to ensure the sustainable provision of ESs. Results The impacts of various land uses on ESs occur in three ways: (1) Major ESs are generated under different land use practices, (2) land use patterns have a significant impact on ESs, and (3) differing intensities of land use may have different impacts on the generation of ESs. As human needs for different ESs vary and are not always consistent, maximizing the use of one ES can lead to a sharp decline in other ESs that may exceed a threshold inducing irreversible change. Therefore, trade-offs between ESs have become challenges that the ecosystem planning and management community must address. Furthermore, other problems (such as a lack of reliable data, inconsistent evaluation methods, and a lack of validated results used in assessments of ESs) compound the difficulty of this challenge. The development of comprehensive assessment models that result from an integrated assessment and scenario analysis of ESs under different land uses can inform ecosystem management options. Future perspectives and conclusions Studies of ESs under different types of land use change must enhance understanding of topics that link ecosystem processes with ESs. Recommended research includes enhancement of the management practices of soil and land, modeling and mapping the spatial flow of ESs, analyzing trade-offs and synergies between multiple ESs, and integrating and optimizing analyses of ESs. By understanding the ecological processes that drive ESs and how these are affected by land use change, we can establish a sustainable balance between multiple uses of different ESs.

“…The conservation of key corridors in these reserves can maintain the integrity of the whole corridor network at regional scale. The maintenance of corridors within the national nature reserve not only offers species short-term opportunities for dispersal or foraging, but also guides the planning framework for land use and maintains landscape integrity in heterogeneous environments (Bennett, 2003;Shen et al, 2014). However, appropriate extensions of corridor outside the reserves in some cases would increase the conservation of regional landscape connectivity.…”

“…Dispersal corridors are movement paths for animals, which connect different habitat patches, and thus offer species practical connections that allow passage through the landscape; they play an indispensable role in functional connectivity of the landscape (Haddad, 1999;Bennett, 2003;Pascual-Hortal and Saura, 2006). For faunal species, corridor networks act as necessary natural pathways for seasonal migration, food acquisition, and daily movements (Bright, 1998, Gilbert-Norton et al, 2010Shen et al, 2014). However, frequent human disturbance has resulted in the increased sensitivity and fragmentation of environments necessary for wildlife survival (Roever et al, 2013;Loro et al, 2015;Gray et al, 2016).…”

Ecological corridor networks can efficiently improve regional landscape connectivity. Corridors for multiple faunal species movements are receiving increasing attention and graph theory is considered a promising way to explore landscape connectivity. In Xishuangbanna, the circuit theory was applied to explore the corridor networks for biodiversity for the first time. In addition, disturbances caused by the road network and the protection efficiency of National Nature Reserves and planned area for corridors were evaluated. Results indicated that the regional corridor networks could be estimated using a modified circuit method and Zonation model. Spatially, the key corridors were concentrated in the central-western, southeastern and northern regions. We detected 66 main intersections between key corridors and the road buffer. Of these points, 65% are forest, 23% grassland and 12% farmland. More than half of the area of National Nature Reserves constituted the top 50% of the corridors, and the planned corridor areas could efficiently protect some key corridors. However, these reserves only protected about 17% of regional key corridors, and the corridor conservation area in the western and northern regions were absent. The issues addressed in our study aided in the elucidation of the importance of regional landscape connectivity assessments and operational approaches in conservation planning.

“…The structure-function correlation is a basic principle of geographic research [1,2], of which coupled studies on landscape patterns and ecological function in Landscape Ecology [3] are an important aspect. Most previous studies on the influence of land use on ecological function or vegetation activity have mainly focused on the type transformation and quality alteration [4][5][6].…”

Based on the theories of structure–function correlation in Geography, and landscape pattern-ecological function correlation in Landscape Ecology, the correlation between land use fragmentation and vegetation activity was quantified. Effective mesh size (meff) was calculated to represent landscape fragmentation for land use, and the normalized difference vegetation index (NDVI) was used to reflect vegetation activity. The geographically weighted regression (GWR) model was applied to explore the spatial non-stationary relationship between meff and NDVI in a karst basin of the southwestern China, where environmental factors (i.e., climate, topography, and vegetation) are spatially heterogeneous. The spatial variation and scale dependence of landscape fragmentation and its relationship with vegetation activity, as well as the influence of lithology types and landforms relief, were considered. Firstly, the optimal ‘slide window’ size for landscape fragmentation was determined to be 500 m, and spatial pattern of meff displayed clear heterogeneity with a serious degree of fragmentation. Landscape fragmentation was more severe in carbonate areas than non-carbonate areas, reflecting the influence of landforms relief. More serious fragmentation in dolomite areas meant that the impact of human activities on the landscape morphological characteristics was much more significant than that in the limestone areas with steeper slope. Multi-scale analysis was used to verify a neighborhood size of 7 km for GWR in the study area. Negative effects on vegetation activity from landscape structural changes were more significant in limestone areas, which may be due to the more vulnerable ecosystems there. This research can provide scientific guidance for landscape management in karst regions as it considers the multi-scaled and spatially heterogeneous effects of lithology, geomorphology, and human factors on landscape structure and its correlation with vegetation activity.
