The results show: There are 231 species of 191 genus in 90 families, including 5 families, 9 genus and 11 species of gymnosperms, and 82 species of 182 genus and 85 species of angiosperms. The 14 distribution types of seed plants belong to the statistics: North temperate distribution There are 72 genus, accounting for 37.7% of the total genus of the area, reflecting the obvious north temperate nature of the flora. In addition, there are many ancient taxa and Cretaceous and Tertiary relict plants. There are 163 genus of single genus and genus genus, accounting for 85.3% of the total genus of the region, indicating that the plant origin is relatively old, there are 7 genus in China, which indicates that the unique phenomenon exists, but it is not obvious.

Based on route and sample-plot survey, plant resources of Liangzi Lake Wetland Nature Reserve were investigated. The result showed that there were 503 species of spermatophyte belonging to 296 genera of 86 families. There were 5 species under national first and second level protection. The dominant families of spermatophyte contained 20 species and above. The dominant genera of spermatophyte contained 4 species and below. The 86 families of spermatophyte can be divided into 7 distribution types and 4 variants. Tropic distribution type was dominant, accounting for 70.83% in total (excluding cosmopolitans). The 296 genera of spermatophyte can be divided into 14 distribution types and 9 variants. Temperate elements were a little more than tropical elements, accounting for 50.84% and 49.16% in total (excluding cosmopolitans) respectively. Reserve had 3 Chinese endemic genera, reflecting certain ancient and relict. The purpose of the research is to provide background information and scientific basis for the protection, construction, management and rational utilization of plant resources in the reserve.

The efficient utilization of plant resources is a necessary and important measure for sustainable management of constructed wetlands. Screening bioactive metabolites from wetland plants could reveal potential solutions for the utilization of constructed wetland plant resources. In this study, the constructed wetland macrophyte Nymphoides peltata was screened for constituents with antitumor activity. The secondary metabolites of N. peltata were extracted and separated by MCI gel, silica gel, and Sephadex gel column chromatography. Antitumor tests were then carried out with MTT assay against the human prostate cancer cell PC3 and the human osteosarcoma cell U2OS. The secondary metabolite group with the most significant antitumor activity was further examined, and four constituents were obtained and identified. This study provides a scientific basis for the potential efficient utilization of N. peltata and other constructed wetland plant resources.

Plant Origin

Since the rise of photosynthesis, life has influenced terrestrial atmosphere, particularly the O2 and the CO2 content (the latter being originally more than 95%), changing the chemistry of waters, atmosphere, and soils. Billions of years after, a far offspring of these first unicellular forms conquered emerging lands, not only completely changing landscape, but also modifying geological cycles of deposition and erosion, many chemical and physical characteristics of soils and fresh waters, and, more, the cycle of various elements. So, there are no doubts that vascular plants modified geology; but it is true that also geology has affected (and, more, has driven) plant evolution. New software, PyRate, has determined vascular plant origin and diversification through a Bayesian analysis of fossil record from Silurian to today, particularly observing their origination and extinction rate. A comparison between PyRate data and geological history suggests that geological events massively influenced plant evolution and that also the rise of nonflowering seed plants and the fast diffusion of flowering plants can be explained, almost partly, with the environmental condition changes induced by geological phenomena.

Reservoir immersion is an environmental geological issue. Jiangxiang reservoir was taken as an example, where both analytical and numerical methods were employed to calculate the banked-up water level after reservoir impoundment, based on the hydrological, meteorological, geological, and hydrogeological conditions. The capillary rise height of soils in the reservoir area was determined through in situ measurement and laboratory analysis. The depth of foundation and crop roots in residential areas can be obtained by field investigation. The critical depth to groundwater was calculated according to the height of capillary rise and land elevation. Furthermore, the influence of reservoir immersion was evaluated, which provides a scientific basis for the relocation of people in reservoir areas, planting of crops, and project investment.

Abstract Background: Huangqi is a famous Chinese medicinal material whose Dao-di producing area is Hunyuan, Shanxi. Huangqi produced in Hunyuan, Shanxi, were divided into several different specifications and grades according to the diameters and different positions of root system. Objective: This article investigates the quantitative characteristics of chemical compositions in different specifications and grades of Astragalus membranaceus var. mongholicus roots, aiming to elucidate the correlation between specifications and/or grades and chemical compositions in Huangqi. Methods: Based on the field investigation, samples of Huangqi collected from Hunyuan, Shanxi, were divided into different specifications and grades. The content of seven flavonoids and five saponins in Astragalus membranaceus var. mongholicus roots of different specifications and grades were determined simultaneously by HPLC–diode–array detection–evaporative light-scattering detection (HPLC–DAD–ELSD). Results: Huangqi was processed by traditional methods, and its commercial specification was classified by different parts of the root system, such as ge-da-tou, hong-lan-qi, zheng-bai-qi, fu-bai-qi, mao-wei-zi, and qi-jian. The total content of seven flavonoids and five saponins in ge-da-tou, qi-jian were lower. The total content of seven flavonoids in hong-lan-qi was much higher, while that of five saponins was much lower. The total content of seven flavonoids in lateral roots or fibrous roots were higher, and that of five saponins was lower, such as zheng-bai-qi, fu-bai-qi, and mao-wei-zi. According to the root diameters, Huangqi was classified to special grade, grade I, grade II, grade III, grade IV, or grade V. Among six grades of Huangqi, the total content of seven flavonoids in grade III, grade IV, and grade V were lower, while the total content of five saponins in them were much higher. Conclusions: There is an obvious difference on the distribution pattern of contents of seven flavonoids and five saponins in Huangqi of different specifications and grades, which provide a certain scientific basis for the quality evaluation of Huangqi. Highlights: The content of seven flavonoids and five saponins in Huangqi were determined by HPLC-DAD-ELSD. The relationship between the commercial specification grades and chemical components of Dao-di herbs Astragalus membranaceus var. mongholicus (Huangqi ) from Hunyuan, Shanxi were revealed, which provided a chemical basis for the classification of commercial specification grades of dao-herbs Astragalus membranaceus var. mongholicus (Huangqi ) from Hunyuan, Shanxi.

The world has huge floral diversity, whereas there often is poor and irrational utilization, especially of indigenous plants and residues from agricultural processes. Trees, shrubs, and herbs can have multiple uses at different levels as medicines and sources of lignocellulosic materials. A fuller and more rational utilization is needed, with interaction of international and national communities, to raise the awareness of local people, governments, and industrial entrepreneurs of the floral wealth that is waiting to be utilized more effectively.
