Exploring the Relationship between Ecosystem Services under Different Socio-Economic Driving Degrees

The large-scale transformation of natural ecosystems to socio-economic development land types under human activities was a primary reason for the decline of regional ecosystem services. It is a key issue for regional ecosystem planning and management to reveal the relationship between ecosystem services of different land use types under different socio-economic driving degrees. However, the current related research was not in-depth. Based on the land use data of Wuhan City in 1980, 1990, 2000, 2010, and 2020, this study classified land use into three categories according to the different degrees of human activities on natural ecosystem development: the land use of a natural ecosystem (LUNE), the land use of a productive ecosystem (LUPE), and the land use of a socio-economic system (LUSE). The InVEST model was used to simulate five ecosystem services (grain yield, water yield, carbon storage, habitat quality, and water purification), and the spatio-temporal distribution and functional transformation of the three land use types were analyzed. Results showed that with the intensified urban expansion in Wuhan, the LUSE types increased to 2.7 times that of the original. However, the natural land types basically maintained a stable area, coupling with the large-scale transformation between the LUPE and LUSE types. Land use change resulted in significant spatial changes of five ecosystem services, especially carbon storage and habitat quality. The correlation analysis indicated that the five kinds of ecosystem services mainly showed a synergistic relationship, meanwhile the LUSE type denoted the most significant correlation with ecosystem services among these three category types. This study indicated that besides the protection of natural ecosystems, the LUSE type would become the key land use type in the planning and management of improving regional ecological function.

[Study on relationship between efficacy against lung cancer and different parts of Schizonepeta tenuifolia based on microfluidic chip technology]

In order to further clarify the rational use of different medicinal parts of Schizonepeta, microfluidic technology was used in this study to investigate the differences in drug efficacy against lung cancer in vitro. The ethanol extracts were examined with HPLC to establish their fingerprints in order to analyze the relationship between the spectrum and efficacy index through Grey Correlation software, and a rapid HPLC-Q-TOF/MS method was established. The result in vitro shows that the effect and components of different medicinal parts had a certain differences, and apoptosis and necrosis rate from big to small in turn is leaf, flower, root, stem. The chromatographic peaks of the 26, 12, 2, 6 and 15th are the luteolin, icynaroside, rosmarinic, caffeic acid, and hesperidin, while the 20 and 10th may be dan phenolic acid L and benzoic acid. On the one hand, preliminary study reflects that the root of Schizonepeta tenuifolia may be developed into the medicinal parts in future. On the other hand, the major chemical composition of S. tenuifolia was found to have the anti-lung-tumor effects. This new method was established for the quality control and the rational use of different parts of traditional Chinese medicine.
