Embodiment approach

[0011] Through research, based on background data such as vegetation coverage and biomass in the target area, set up the technical details of balanced harvesting and ecological water saving.

[0012] According to the physiological characteristics of the harvesting objects, the methods of vertical harvesting and horizontal harvesting are adopted respectively. Vegetation that is easy to tiller is generally harvested vertically, and other vegetation is harvested horizontally.

[0013] Balanced harvesting occurs before vegetation water consumption is at its maximum. The time for horizontal harvesting is from May to June, and the time for vertical harvesting is from June to July. The ratio of balanced harvesting is between 10% and 30% according to the different water saving goals. During vertical harvesting, the vegetation community is evenly arranged in strips along the vertical direction of the dominant wind direction in the target area, and the vertical harvesting is carried o...

Embodiment 1

[0016] For a certain lake in the Haihe River Basin, using the present invention as an ecological water-saving technology, the local vegetation is harvested in a balanced manner, with a harvesting ratio of 20%. The water consumption and its water-saving effect are shown in the following table:

[0018]

Embodiment 2

[0020] For the reeds in an ecological park in Beijing Yizhuang Milu Garden, using the present invention as an ecological water-saving technology, the vegetation is harvested in a balanced manner, with a harvesting ratio of 30%. The water consumption and water-saving effect are shown in the following table:

Abstract

The invention provides an ecological water-saving method for realizing water-saving effect by a balanced reaping technology, which aims at the characteristic that a vegetation water supply condition can not be artificially controlled under a natural condition. On the basis that physiological and ecological parameters of vegetation type biomass, leaf area indexes, and the like are stable, an ecological water-saving purpose is realized. Reaped vegetation residues are remained at an original place to play better covering and water-saving effect. On a premise that the basal physiological activity and the ecological function of a vegetation type are not influenced, the balanced reaping ecological water-saving technology realizes a reducing purpose of ineffective moisture consumption and achieves an ecological water-saving purpose. The ecological water-saving method has simple and convenient operation, practicability and obvious water saving effect, overcomes a set that the water saving starts from irrigation, radically realizes the high-efficiency use of water resources and effectively solves the problem of ecological water saving of a vegetation type system in the natural ecosystem.

Description

technical field [0001] The invention belongs to the field of environmental science and restoration ecology, and in particular relates to a balanced harvesting ecological water-saving technology and method. It can realize the regulation of water consumption of vegetation communities under natural conditions and under the premise that water supply conditions cannot be controlled artificially. Background technique [0002] The northern part of my country is an arid and semi-arid area. In recent years, the contradiction between the protection of the regional ecological environment and the development of the regional economy has become increasingly acute. On the one hand, the lack of water resources has increasingly become an important factor restricting my country's economic and social development. The national water shortage in normal years is about 40 billion m 3 , the reduction of the total amount of available water resources has made the conflict between local economy and ...
