Embodiment 1

[0034] With the development of science and technology, the theory and application of ArcGIS in various fields of ecology are becoming more and more extensive, for example: ArcGIS is used in landscape ecology, marine ecological environment monitoring, farmland ecosystem, using ArcGIS to calculate ecological carrying capacity, and ArcGIS to do ecological risk Spatial distribution map and so on. Moreover, ArcGIS technology is becoming more and more mature and has become an indispensable technology in the field of ecology. Therefore, this embodiment uses ArcGIS to complete the calculation of plant leaf area.

[0035] The present embodiment provides a method for measuring the leaf area of ​​a plant, specifically as Figure 1 to Figure 6 shown, including the following steps:

[0036] Step 1: Collect plant leaves in the wild, and the collected leaves can be in any shape, such as flakes, strips or needles;

[0037] Step 2, taking pictures of the collected plant leaves to obtain the ...

Abstract

The invention provides a method of measuring an area of a leaf of a plant and belongs to the technical field of physiological plant ecology research. The method comprises the steps of collecting a leaf of a plant, taking a photo of the leaf of the plant, converting the photo format, determining TIC point coordinates, identifying the photo by using eCognition software, reading the length, the widthand the topology of the leaf by using a scaleplate in the ArcMap and obtaining data to obtain the leaf area. The method is low in cost, flexible to operate and precise in measurement, saves time, solves the problem of irregular leaf and small leaf area measurement and calculation efficiently, reduces artificial error and can be stored independently and read again. The method can measure the leafarea of any plant leaf, is very convenient to operate outdoors and can measure a large number of samples. A computer directly measures the line and plane information, so that the method well reduces error caused by subjective influence; and each built vector files can be stored independently and read again for next convenient use.

Description

technical field [0001] The invention belongs to the technical field of plant physiological ecology research, and in particular relates to a method for measuring plant leaf area. Background technique [0002] Plant functional traits are easy to observe and measure, and are the result of species adapting to different environments during the long-term evolution process, which can objectively express the adaptation and response of plants to the external environment. Plant functional traits can respond to changes in habitat and have certain effects on ecosystem functions, reflecting the indicator role of plants in characterization of ecosystem functions, and reflecting the relationship with ecosystem processes and functions. Leaf traits play a key role in the process of plant functional traits responding to ecosystems, and leaf area measurement is essential in leaf traits. [0003] At present, the measurement of plant leaf area is mainly carried out by means of a portable laser ...
