Embodiment

[0058] In the source area of ​​the Tarim River Basin, based on the need to protect and restore the ecosystem of the mainstream river, the river ecological restoration system was adopted, and the degree of guarantee of the water discharge from the source area to the main stream was continuously improved after the implementation of the "big watershed" comprehensive management model. In 2011, when the comprehensive management of the "Great Watershed" was implemented, the anomalous percentage of the source runoff was -4.1%, and the anomaly percentage of the main stream runoff was 12.6%, while in 2008, the anomaly percentage of the source runoff was -1.8%. The percentage anomaly of dry runoff is -37.5%. At different time periods, before the implementation of the "big watershed" comprehensive management (2006-2010), the runoff from the source stream to the main stream accounted for 18.0% of the source stream runoff, and after the implementation (2011-2017), it increased to 22.3%. Th...

Abstract

The invention discloses a river ecological restoration system. The river ecological restoration system comprises a river ecological data analysis system and an ecological implementation system, the analysis method of the river ecological data analysis system specifically comprises the following steps of S1, water balance calculation, S2, leaked water calculation and S3, separation and reasoning ofthe climate change and human activities on the water resource influence quantity. The invention relates to the technical field of basin resource protection and utilization. According to the river ecological restoration system, the guarantee degree of drainage basin ecological water, the natural vegetation coverage and the change characteristics of soil drought are compared and analyzed before and after large drainage basin comprehensive management, and the guarantee effect of a large drainage basin comprehensive management mode on ecological water supply under the climate change background is quantitatively evaluated;; by constructing a quantitative relation model among river runoff volume, seepage quantity and a tree annual ring standard annual table, a new idea of reconstructing riverseepage quantity by using the tree annual ring standard annual table is provided, and water resource optimization management of a similar drainage basin in an arid region is realized.

Description

technical field [0001] The invention relates to the technical field of watershed resource protection and utilization, in particular to a river ecological restoration system. Background technique [0002] Building a reasonable and efficient watershed management system is of great significance to ensure the ecological water demand of natural vegetation in arid areas and maintain the integrity and stability of fragile ecosystems. In arid regions, how to evaluate the effectiveness of watershed management on ecological protection and how to realize the optimal regulation and efficient use of ecological water have become the focus of attention of many scholars and watershed managers. [0003] Due to the shortage of water resources, lagging economic and social development and fragile ecological environment, arid watersheds are one of the key areas in the study of global environmental change and sustainable development. In recent years, due to the comprehensive impact of climate ch...
