Evaluation Of Agricultural Landscape Ecosystem Services In Zhaozhou County

One of the core factors in the rational allocation of agricultural resources is to conduct a rational research on the modern agricultural landscape system and improve the ecosystem service function of the agricultural landscape to build a sustainable ecological agriculture.The ever-increasing unscientific development and utilization have caused the landscape ecological service function of agricultural resources to gradually decline.How to reasonably evaluate the ecosystem service function of agricultural landscape is an effective way to maintain the health of agricultural landscape.Existing studies establish the ecosystem service of agricultural landscape directly on the basis of land use classification.The change of land type will inevitably lead to the change of ecosystem function.However,the integrity of both the agricultural landscape function and the ecological process has been greatly disrupted,which has had a huge impact on the development and promotion of the comprehensive value of agricultural landscape.Based on this study,the agricultural landscape type is rich in Zhaozhou County as the research object,combined with the theory of ecosystem services and other methods to combine different agricultural landscape types and ecosystem service evaluation to reveal the agricultural landscape unit in the ecosystem services.First,this study used the dominant functional morphology classification method to select regional landscape types,land use classifications,and soil types of agricultural landscapes as indicators for the classification of agricultural landscapes,and adopt a three-level classification system for agricultural landscapes,agricultural landscape subtypes,and agricultural landscape units.Research on the classification of agricultural landscape in Zhaozhou County.Through the extraction of agricultural landscape research scope,division of dominant factors,selection of indicators to build a classification framework.The agricultural landscape of Zhaozhou County was divided into 1 landscape,5 landscape sub-categories and 60 landscape units.Then,the evaluation unit was locked into a landscape unit through the results of agricultural landscape classification in Zhaozhou County,and 14 secondary indicators were selected from three aspects of ecosystem service value,ecosystem service function index and ecosystem aesthetics to construct an agricultural landscape ecosystem service evaluation system.Using the coefficient of variation method,the analytic hierarchy process,and qualitative and quantitative analysis to determine the index weights,the ecosystem service evaluation of agricultural landscape units was conducted.Finally,according to the evaluation results,the differences of agricultural landscape ecosystem services in Zhaozhou County were analyzed,and related suggestions for agricultural landscapeecological construction were proposed from the perspective of sustainable agricultural development and land use.The main conclusions of the study are as follows:(1)Evaluate the ecosystem service function based on the objective and operable agricultural landscape classification suitable for the natural and social background conditions of Zhaozhou County.Not only can fully reflect the function and structural characteristics of agricultural landscape,but also can guarantee the homogeneity of ecosystem service evaluation object,and make the evaluation result more effective.(2)Through the existing research,the combination of qualitative and quantitative methods is used as a classification method to more scientifically divide the differences in the characteristics of agricultural landscape,and then combined with multiple in-depth investigations to verify the results.The classification results are consistent with the actual situation of agricultural landscape in Zhaozhou County.This method is applicable to the classification of agricultural landscape in Zhaozhou County.(3)The result of ecosystem service evaluation shows that there are great differences in the agricultural landscape ecological services in Zhaozhou County,and the value of the agricultural landscape units after weighted treatment is: 0.1798-0.6589,showing a clear trend from west to east.Only 6 landscape units are the “highest” levels of ecosystem services.Although the landscape ecological function is more prominent,it accounts for one-tenth of the total landscape units.In addition,the ecological function of landscape units decreased with the increase of elevation and slope in spatial distribution,and the sub-categories of landscape services of all landscapes were expressed as arable land landscape subcategories> woodland landscape subcategories> grassland landscape subcategories> watershed landscape subcategories trend.(4)According to the evaluation results,we hope to solve some problems encountered in the development of agricultural landscape ecological services in Zhaozhou County,and put forward relevant suggestions for land use and sustainable agricultural development.This will increase the overall level of agricultural development in the county,effectively stimulate economic growth,and have a profound impact on achieving agricultural efficiency.
