“…The implementation of ECR is an institutional innovation for Chinese ecological conservation. ECR is being indentified as ecological baselines for the protection of the environment and its resources [18]. ECR in Heze was delimited by the overlay of important areas of ecosystem services function and the areas of ecologically environment sensitive, as well as the prohibited development and other important protected areas.…”

With the overall trends of deterioration in resources and ecological environments not being completely reversed, the Chinese government has adopted the strategy of establishing the Ecological Conservation Redline (ECR). The ECR aims to define limits to the encroachment onto protected ecologically vulnerable and sensitive areas, to prohibit development in these areas, and to enforce strict protection to guarantee regional ecological security. Climate data, remote sensing data, and other related data were used to identify an ECR in Heze, thereby providing an example of principle and methodology for ECR delimitation. After assessment, comprehensive treatment, and coordination analysis, a total area of 924.17 km2, accounting for 7.55% of the city’s total area, was identified as an ECR in Heze. This mainly comprised the area around the Yellow River, the old course of the Yellow River, and the Dongyu River.

“…The demarcation of EPRs is typically based on ecological sensitivity and the importance of the ecological service function. These delineations can be assessed by several factors, including neighborhood factors and topographical conditions [9]. For designating BFPZs, including land location, the soil quality, agricultural infrastructure, and topographical conditions are must be considered [18,25,35].…”

“…Meanwhile, large-scale cultivated land and natural areas are occupied, which will cause damage to food supplies and ecological security [5][6][7]. Hence, coordinating relations among construction land, cultivated land, and ecological land is pivotal for sustainable urban development [8,9]. Protecting sufficient amounts of cultivated land and natural areas has become essential, and a matter of worldwide concern with regard to urban land policies in recent years [10,11].…”

“…UGBs have been widely used in many countries and regions, such as London's Metropolitan Green Belt, Holland's Green Heart, and Melbourne's UGBs [14][15][16]. In addition to UGBs, several LMRLs have been developed to restrain the conversion of farmland and ecological lands, such as exclusive agriculture zones in Oregon, ecological protection redlines (EPRs), and basic farmland protection zones (BFPZs) in China [9,17,18].…”

“…Among them, UGBs are used to guide smart urban growth, thus constraining urban construction lands to a fixed area, and promoting compact developments within a city [8]. EPRs, which contain areas with vulnerable ecosystems or important ecological functions, are the baselines and barriers of urban ecological security, thereby maintaining urban ecosystem services [9,24]. BFPZs are delimited for protecting basic farmland from the threats of construction, thus ensuring food security [25,26].…”

The delimitation of three land management red lines (LMRLs), which refers to urban growth boundaries (UGBs), ecological protection redlines (EPRs), and basic farmland protection zones (BFPZs), has been regarded as a control method for promoting sustainable urban development in China. However, in many Chinese cities, conflicts extensively exist among the three LMRLs in terms of spatial partitioning. This study clarifies the connotation of conflicts among the three LMRLs. Moreover, a red line conflict index (RLCI) is established to characterize the intensity of conflicts among the three LMRLs. The Wuhan Urban Development Area (WUDA) is used for a case study, in which the spatial patterns of the three types of conflicts among the three LMRLs (i.e., conflicts between EPRs and BFPZs, EPRs and UGBs, and UGBs and BFPZs) are analyzed through numerous spatial statistical analysis methods (including spatial autocorrelation, urban-rural gradient, and landscape pattern analyses). In addition, the driving forces of these conflicts are identified from the perspectives of natural physics, socioeconomic development, neighborhood, policy and planning using three binary logistic regression models. Results show that the conflicts between EPRs and BFPZs, EPRs and UGBs, and UGBs and BFPZs are mainly distributed on the edge of the WUDA, inside Wuhan’s third circulation line, and at the urban–rural transition zone, respectively. The patch of conflict between BFPZs and UGBs has the lowest aggregation degree, the highest fragmentation degree, and the most complex shape. Logistic regression results show that the combination and relative importance of driving factors vary in the three types of conflicts among the three LMRLs. In the conflict between EPRs and BFPZs, the distance to city centers is the most important influencing factor, followed by the proportion of ecological land and elevation. In the conflict between UGBs and EPRs, the proportion of construction land, the distance to city centers, and whether the land unit is within the scope of a restricted development zone are the three most important factors. The proportion of construction land, the distances to the Yangtze and Han Rivers, and the proportion of cultivated land significantly influence the conflict between UGBs and BFPZs. This study aids in our understanding of the causes and mechanisms of conflicts among the three LMRLs, and provides important information for the “integration of multi-planning” and land management in Wuhan and similar cities.
