Design and implementation of plant retrieval system in Yuzhong County, Gansu Province

The identification and classification of herbaceous plant species is an important component of grassland resource surveys and related scientific research and teaching. With the continuous development and application of computer technology, new means and methods are provided for the construction, classification, and retrieval of plant image databases. In this study, we established a resource information database of common herb image data in Yuzhong county, Gansu province, including 13 families and 256 species of common herbs, based on the Access platform. On this basis, a plant retrieval system for the area was designed and developed using the VBA language. The accuracy evaluation results showed that when the input morphological information number was 3, the plant recognition rate could reach over 70% except for Gramineae. When the input morphological information number was 6, the plant recognition rate could reach over 80%, although the recognition rate of Plantaginaceae, Cyperaceae, Salviaceae, and Tribulus could reach 100%. The identification accuracy of the system to various herbaceous plant families is high, the system operation is simple and easy, the visualization effect is good, meeting most of the user requirements.
