| As one of the rarest and most endangered birds in the world,the crested ibis has been greatly disturbed under the influence of comprehensive ecological problems such as natural ecosystem degradation,biodiversity loss,and land desertification.The latest observation and research found that the crested ibis’ growth rate fluctuated greatly and its habitat activity trajectory expanded to the entire Hanzhong Basin,indicating that its habitat has undergone relatively obvious changes,especially the paddy field habitat,which is the main foraging ground of crested ibis,is the survival and development of crested ibis.It is also an important carrier for ensuring the stable growth of its population.As a key habitat for crested ibis,paddy fields have declined in the Yangxian-Chenggu area in recent years,due to the severe inclination of paddy fields in space and time distribution,the relatively low quality of paddy field habitats,and the excessive disturbance of human activities,resulting in high fragmentation of paddy field habitats,As the main foraging grounds in the key ecological cycle,the habitat pattern is single and the food abundance is seriously insufficient.The current large-scale paddy fields are not particularly suitable for crested ibis foraging habitats.This is the main reason for the expansion of crested ibis and the abnormal growth rate.With the concerted efforts of the whole society in the past half century,the conservation of crested ibis has achieved considerable results.However,the status of its main habitats is still not optimistic,especially the key habitats in paddy fields.The current research on the coupling relationship between paddy field habitats and crested ibis habitats is lacking.How to protect,restore and rationally use paddy field habitat based on the comprehensive background of ecological restoration is the top priority of this research.The main contents of this research are as follows:To sort out related habitat restoration paradigms.Through the literature review of ecological restoration at home and abroad and habitat restoration from the perspective of related disciplines,the methods and paths of ecological restoration are summarized;combined with the team’s existing research logic system framework,the uniqueness and typicality of the research object and research scope are clarified respectively.,to derive a conventional paradigm of habitat restoration methods.Yangxian-Chenggu crested ibis habitat and paddy field habitat analysis.The crested ibis activities related to paddy fields were screened and the key locations of typical regions were summarized based on the latest results of the investigation in the spring and autumn.A habitat evaluation system for paddy field habitats in key foraging grounds was established,and a spatial prototype of paddy field habitats with high suitability was obtained in combination with AHP.The typical habitat factors and practical problems of paddy field habitats in the region were comprehensively obtained from the relationship between the changes of landscape pattern index over the years and the number of crested ibis,key habitat locations and foraging behavior,combined with field observation data.To construct the Yangxian-Chenggu crested ibis habitat restoration method system for paddy field habitat.Combined with the theory of natural grade and scale effect,it realizes the leap from a purely ecological perspective to the field of landscape ecological planning and design linked by the discipline of landscape architecture,and provides rich realization scenarios and approaches for the specific implementation of habitat restoration.The spatial expression of the prototype landscape diagram of the paddy field habitat is taken as the restoration goal.From the perspective of landscape architecture,combined with its specific means and methods,aiming at the typical habitat factors and the current situation,the strategies,methods and governance routes of paddy field habitat restoration are obtained in layers and applied to practice.The key conclusions of this study are as follows: First,based on the current era of ecological restoration of national land space,with landscape architecture as a link combined with landscape ecological planning and other related disciplines,through the research on the restoration of the paddy field habitat of the crested ibis habitat in Yangxian-Chenggu,Shaanxi Province,the landscape is obtained.The planning and design method system is secondly applied to the practice of planning and design of the restoration of crested ibis habitats in paddy fields during wintering and breeding periods,to solve the current practical problems of crested ibis key habitats in paddy fields and provide reference for the construction of key habitats for crested ibis to be introduced into ex situ conservation.pattern method.More importantly,the research process of landscape planning and design methods for the restoration of paddy field habitats for crested ibis habitats in Yangxian-Chenggu,Shaanxi Province,can provide a logical reference and basis for the research on habitat restoration of related animal and plant habitats in the context of the new era,which is fundamentally helpful.To reconcile the opposing relationship between man and nature. |
