将生态系统服务纳入耕地多功能的权衡协同评估和分区管理
Temporal and Spatial Trade-offs between the Production,Livelihood,and Ecological Functions of Cultivated Land from the Perspective of Ecosystem Services
摘要
Abstract
The land system is a complex ecosystem of multidimensional interactions among human activities,socio-economics,and natural ecology,playing a key role in promoting ecological stability and sustaining human life.It provides extensive ecosystem services(ES)to humanity across the production,living,and ecological dimensions,including provisioning,regulation,and cultural services.In the land system,different ES functions exhibit a complex interdependence or trade-off relationship with human social systems.The Yangtze River Economic Belt(YREB)is one of China's most important grain production areas.The rapid urbanization process has led to the expansion of urban areas,which has encroached upon existing farmland resources.According to the third national land survey,China's farmland area has decreased by 113 million acres,facing intensified pressures on natural resources and environmental degradation,as well as challenges such as farmland-based pollution,with the potential for developing reserve farmland resources being undermined.Therefore,this study adopts the perspective of ES to explore the spatiotemporal evolution patterns and the trade-off and synergy effects of the farmland production-living-ecology functions.Based on this,it proposes differentiated and refined management zoning and control pathways,which have profound practical significance for ensuring China's farmland security and food security.In this context,this study selects eight indicators,including food supply(FS),cultivated land carrying capacity,agricultural economic density,density of agricultural labor force,water yield(WY),soil and water conservation(SR),carbon sequestration(CS),and habitat quality(HQ),using the land use transfer matrix,the InVEST model,and the trade-off and synergy model.It constructs the 2000‒2020 farmland"production-living-ecology"evaluation system for the YREB,exploring the trade-offs and synergies between farmland's multifunctionality,identifying farmland function zoning in the YREB,and proposing differentiated land zoning optimization pathways.The main conclusions are as follows:Overall,between 2000 and 2020,there was a significant transfer effect between farmland and other land use types in the YREB.Specifically,from 2000 to 2020,the total area of farmland transfer and out of the YREB was 235146 km2,accounting for 11.5%of the total farmland area.From the perspective of farmland transfer out,the total area of farmland transferred to other land use types was 105061 km2.Among them,paddy fields and dry land were primarily transferred to forest land and built-up land,with transfer areas of 53248 km2 and 51813 km2,respectively.From the perspective of farmland transfer in,the total area of land types converted into farmland was 74505 km2.Among them,the newly added paddy fields were transferred from forest land,with a total inflow area of 31486 km2.In contrast,the newly added dry land was mainly converted from forest land,with a total inflow area of 43019 km2.From the perspective of production function,the high-value areas of farmland the production function are mainly distributed in regions such as the northern Anhui Plain and Jiangsu Plain in the downstream YREB.The medium-value areas for production function are mainly distributed in regions such as the Sichuan Basin and the middle and lower reaches of the Yangtze River Plain.From the perspective of living function,the cultivated land's living function index exhibited a trend of first increasing and then decreasing between 2000 and 2020.In 2000,high-value areas of living function were concentrated in western Anhui,Shanghai,and northeastern Zhejiang Province.Medium-value areas were located in Hubei,Yunnan,and the Sichuan Basin.Low-value areas were mostly distributed in Guizhou Province and southern Jiangsu.Between 2010 and 2020,high-value areas of living function were primarily concentrated in Shanghai,Jiangsu Province,southern Hunan Province,and the Sichuan Basin.Medium-value areas were mainly concentrated in Anhui,Zhejiang,and the Poyang Lake Plain.Low-value areas were mainly distributed in the upstream regions of the Yangtze River Economic Belt,including Yunnan,Guizhou,and Chongqing.From the perspective of ecological function,the ecological function of the YREB farmland system remained at a relatively low level between 2000 and 2020.The high-value areas are mainly distributed in the upstream YREB regions such as Yunnan,Guizhou,and Chongqing.The medium-value and low-value areas span across the middle and lower reaches of YREB,including regions such as Sichuan,Hunan,Hubei,Jiangsu,Shanghai,and Anhui.Between 2000 and 2010,the ecological function of the region declined sharply.By 2020,the ecological function had gradually increased and stabilized.From the perspective of the integrated"production-living-ecology"function of farmland,the threefold function of YREB farmland showed an evolution pattern of initial increase followed by a decrease between 2000 and 2020.From the perspective of the trade-off and synergy effects between production function and living function,overall,the production function and living function of the YREB farmland system mainly show a slight trade-off.Among them,39.97%of the counties show varying degrees of synergy,50.78%exhibit trade-off relationships,and 9.52%of the counties show no correlation or insignificant relationships.From the perspective of the trade-off and synergy effects between production function and ecological function,overall,a slight synergy is observed.Among them,51.38%of the counties show varying degrees of synergy,42.73%display varying degrees of trade-off relationships,and 5.89%show no correlation or insignificant relationships.From the perspective of the trade-off and synergy effects between the living function and ecological function,overall,the production function and living function of the YREB farmland system mainly show a slight trade-off.Among them,46.15%of the counties show varying degrees of synergy,46.06%exhibit varying degrees of trade-off relationships,and 7.79%of the counties show no correlation or insignificant relationships.Finally,this study categorizes the cultivated land in the YREB into three functional zones:elastic development zones,production protection zones,and key development zones.For elastic development zones,the study sets management goals aimed at promoting coordinated urban-rural development,alleviating regional ecological pressure,and enhancing the sustainable use of cultivated land.For production protection zones,the goals focus on safeguarding cultivated land security,advancing green and efficient agricultural practices,and jointly strengthening ecological barriers.For key development zones,the proposed goals include integrating urban and rural spatial planning,facilitating industrial integration,and promoting the functional transformation and upgrading of cultivated land.The research results can provide a scientific basis for the"in-out balance"of farmland and food security in YREB.关键词
