Problems solved by technology

At present, this kind of farmland restoration has become a common demand in the whole country. For farmland in ecologically sensitive areas, it can not only restore its damaged ecosystem, but also present a harmonious farmland landscape after a similar natural recovery state. At the same time, it is fast and cost-effective There is still a lack of methods for constructing farmland landscapes with low management and maintenance in the later stage

Embodiment 1

[0051] The method for constructing the landscape of the farmland ecosystem restoration according to the present invention will be further described by taking the farmland around the Qilihai Wetland in Ninghe District, Tianjin as an example in conjunction with the accompanying drawings. Such as figure 1 Shown is the landscape construction method for farmland ecosystem restoration in this area, and the specific steps are as follows:

[0052] Step 1. Ecological environment investigation:

[0053] Through the study of relevant scientific research reports on the farmland surrounding the Qilihai Wetland in Ninghe District, Tianjin, we learned about the current situation and characteristics of natural factors such as soil, water system, and climate in the landscape, and found that there is only a subtype of salinized fluvo-aquic soil in the soil of the landscape type, surveying the existing crops and surrounding wild crops and associated plants, a total of 44 sample plots were surve...

Abstract

The present invention relates to a landscape construction method for farmland ecosystem restoration in ecologically sensitive areas. The method comprises the following steps: A. Investigating the soil, water body, and climate where landscape construction is required, and determining the ecological characteristics of species; B. According to plant morphology and planting methods , ecological habits, community stability, and determine the species and seed quantity ratio of the species used for landscape formation; C. Select an open space in the location where landscape formation is required to conduct a sowing test for screening seeds, and the test variables are the sowing season and planting soil type , seed particle size, seed sowing density; D, through the results of the step C test, the combination with the highest average emergence rate, stable and natural community, and low pressure of artificial management and protection is selected; E, the species combination model obtained from the test and The planting method is implemented in the actual restoration of the surrounding farmland ecosystem that needs landscape formation; F later management; the invention has low cost, less manual management in the later stage, good ecological restoration effect, and full of natural beauty.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a landscape construction method for restoration of farmland ecosystems in ecologically sensitive areas. Background technique [0002] Farmland provides 66% of the world's food supply. It is a complex ecosystem in which humans use the relationship between farmland organisms and abiotic environments and between farmland biological populations to produce food and other agricultural products that humans need. The foundation of development has ecosystem service functions such as maintaining the biogeochemical cycle and hydrological cycle of living matter, maintaining biological species and genetic diversity, protecting soil fertility, and maintaining the balance and stability of atmospheric chemistry. With the development of society and the rapid increase of population, while human beings are enjoying the output of farmland, farmland is degraded due to unsus...
