Study On Soil And Water Conservation Monitoring Of Jinqing Goose Tourist Highway Project

Soil and water conservation is of great significance to the quality of the ecological environment,and it is also an important part of ecological governance.In recent years,with the rapid development of the national economy,there have been numerous production and construction projects.Under the background that the economy is greater than the environment,"resources and environment for development" have become a common development method for all regions.On the contrary,production and life continue to occupy ecological space,ecological environmental problems continue to arise,ecosystem service functions are gradually weakened,and the contradiction between man and nature continues to intensify.In view of this,it is necessary to monitor and study the ecological environment of production and construction projects to achieve the stability of the ecosystem in the project area and enhance the functions of production and construction projects.Golden Sand Beach,Qingliang Mountain,and Emeikou are the most famous tourism resources in Huairen City.The cultural tourism development represented by them is related to the transformation and development of Huairen City and the construction of ecological civilization.However,due to the special geographical environment and ecological environment,Jinqing Goose The construction of the tourist road will inevitably cause soil erosion in the area along the route.Therefore,monitoring the water and soil conservation of the Jinqinge Tourist Road will help protect the ecological environment of the region and realize the ecological concept of not only the golden mountains and the silver mountains but also the green mountains.In this context,this article is based on the concept of green development,relying on the Huairen Golden Beach-Qingliang Temple-Emaokou tourist circulation road project,and discusses the rocky mountainous area from the perspectives of soil science,soil and water conservation,economics and ecology.The difference of soil erosion and the effectiveness of soil erosion conservation measures under the dynamic monitoring of road water and soil conservation in the flood plain area,from the original landform(2010.3),after disturbance(2010.8-2014.12),after treatment(2018.10-2019.10)three time periods Analyze the differential characteristics of regional soil erosion,and finally use data analysis software such as excel and Arc GIS to process and analyze the data.The research results are as follows:(1)According to the soil erosion modulus obtained from monitoring at various stages,it can be seen that the original landform of the monitoring zone has serious soil erosion,and the original landform soil erosion modulus of the monitoring zone of the alluvial plain area reaches 3500t/km2·a.The original landform soil of the rocky mountain area The maximum erosion modulus is 1600 t/km2·a,which are 3.5times and 8 times the respective allowable soil loss.After the disturbance,the soil erosion in the monitoring sub-area further intensifies,and the original landform soil erosion modulus of the alluvial plain is 2800-3500t/ Between km2.a,the soil erosion intensity is moderate erosion.After the disturbance,the soil erosion intensifies,and the erosion intensity rises to strong,indicating that the road construction has brought serious soil erosion problems.The soil erosion modulus of the original landform in the rocky mountain area is between 1500-1600t/km2.a,and the soil erosion intensity is light erosion.After the disturbance,the soil erosion intensity in the rocky mountain area is moderate erosion;the water and soil loss in the monitoring zone after the treatment is obtained Effective treatment,the effect is obvious,the soil erosion modulus of all monitoring districts in alluvial plains is reduced by more than 200% compared with the soil erosion modulus of the original landform.The soil erosion intensity is mild erosion,and the monitoring districts of earth-rock mountainous areas After treatment,the soil erosion modulus was lower than the allowable soil loss of 200t/km2·a,and the soil erosion intensity was all mild erosion.(2)The amount of soil loss at each stage.By comparing the water and soil erosion survey and actual measurement data before and after the construction of the project area,it can be seen that the amount of soil erosion in alluvial plains is higher than that in rocky mountainous areas,and the degree of soil erosion is more serious;the annual soil erosion amount directly doubles after the original landform disturbance in the construction area.The amount of erosion increased from 1050.58 t to 2247.35 t.After the implementation of water and soil conservation measures,the amount of soil erosion was 297.28 t,which is753.30 t less than the original landform and 1950.07 t less than after the disturbance.The intensity of soil erosion has been significantly reduced.It shows that the erosion modulus and the annual soil erosion amount have decreased significantly after taking engineering measures and vegetation measures,and even better than the original landform.The soil and water conservation control measures are effective,and the soil erosion modulus of the monitoring zone in the rocky mountain area also conforms to this law.(3)The amount of soil loss in each monitoring district.The annual soil erosion amount of each monitoring area in the alluvial plain area,whether it is the original landform,after disturbance or after treatment,from large to small,in order of subgrade engineering> construction production and living area>construction access road> bridge and culvert engineering> construction water and electricity,and monitoring in earth-rock mountainous areas The annual soil erosion volume of the districts is subgrade engineering> construction production and living area> borrow yard> spoil yard> construction access road>bridge and culvert engineering> construction water and electricity,whether it is the original landform,after disturbance or after treatment,from large to small.,Roadbed engineering and construction production and living areas have the largest amount of soil loss,which is the main area where production damage occurs,and is also the most important area for disturbing land types.(4)Protection effect of water and soil conservation.After the treatment,the soil erosion modulus becomes smaller,the soil erosion intensity in the project area is reduced,and the total amount of soil loss is reduced,which disturbs the land remediation rate,the total control degree of water and soil loss,the soil loss control ratio,the blocking rate,the forest and grass vegetation restoration rate,the forest and grass The coverage rate and other six indicators all meet the requirements of relevant standards,indicating that the layout of water and soil conservation projects in the project construction area is reasonable,the effect of soil and water conservation monitoring and ecological governance is good,and the water and soil conservation functions and ecological environmental benefits of the areas along the line have been improved.
