| With the rapid development of the global economy and the acceleration of urbanization process in China, there is a series of unprecedented social ecological and environmental problems, most of these problems are related to human over-exploitation of natural resources and unreasonable use. This study found there is a significant relationship between plant diversity and the natural environment. The sustainable development is an important component of the regulatory function of the ecosystem. Species-rich plant communities can play a variety of functions in order to maintain the ecological balance of the ecosystem. Therefore, the investigation and study of plant diversity have been paid more and more attentions.As a typical western arid ecosystems, the plant community composition in Jingtai county was composed with a single, small number of plant species before1970 s,. After that, ecological environment gradually improved Jingtai county with the start of lift irrigation, reforestation and other ecological engineering. Now the ecological environment of Jingtai county has been greatly improved. However, the plant resources in Jingtai county was still undiscovered. Thus, in order to develope and utilize the native plant resources, a comprehensive and systematic investigation was carried out to clarify the diversity of plant resources in Jingtai county.Based on the status in Jingtai county, the main types of green in Jingtai county was divided into four types, including green parks, green roads, subsidiary and other green. The results were listed as below:1) Through the investigation of various types of green space in Jingtai county,Jingtai county garden plants have 70 families, 209 genera and 354 species, accounting for 73% of all wild plants and cultivated plants in Jingtai county. The survey foundthat the forest consists of 20 genera, including spruce on Shoulu mountain and Changling mountain. Wider distribution of trees and shrubs, ornamental plants were concentrated in Shoulu mountain National Forest Park, Changling mountain, Luyang Ditch Wetland Park, and with the introduction of potted flowers, variety, mainly in Luyang, Wufo and Yitiaoshan Town area.2) According to the results, we found that the use of plant diversity in Jingtai county is in a lesser extent currently, few applications of plant species, common species were bolonged to a few families, such as Pinaceae, Salicaceae, Leguminosae,Rosaceae, Compositae, Ranunculaceae, Oleaceae, and so on. Plant color was relatively monotonous and seasonal differences were not obvious. The selected landscape plants were not enough scientific and rational, various types of green plants have identical configuration and design patterns, poor visual effects, or ecological functions were overlooked. Three-dimensional green plant resources were relatively poor, relatively small production applications.3) With the Comprehensive analysis of the status of plant diversity in Jingtai county, suggestions were given out to three different types of organizations, including government, businesses and residents in Jingtai county. This study provides a theotical basis to the development of garden in Jingtai county. |
