Based on the effect of marine environment caused by sea reclamation and Technical Directives for Marine Ecological Capital Assessment(GB/T 28058-2011), the indexes of the loss of coastal ecosystem services led by sea reclamation were built. The lost value of sea reclamation was calculated using three methods, namely, economic evaluation, emergy analysis and biodiversity experiential formula. The three methods were applied in the new sea reclamation in Taxia, Fuding City, Fujian Province, and the total ecosystem lost value was 6.720 million CNY/year, 8.092 million CNY/year, and 1.333 million CNY/year, respectively. Compared with other relevant researches, this paper analyzed feasibility and applicability of the three methods, so as to include project external cost into the project economic profi t and loss analysis in the evaluation of environmental infl uence, and to provide technical support for the sustainable economic development of coastal zones.

In spring,summer,autumn 2015,we studied the seasonal variation of phytoplankton community structure in six rivers within Duobukuer Nature Reserve,and made preliminary evaluation of the water quality in Duobukuer Nature Reserve based on phytoplankton *** results showed that a total of 7 phyla,41 genera,66 species and varieties of phytoplankton were identified in Duobukuer Nature Reserve;the annual species composition was dominated by diatom( 59%) which also preponderated in dominant species( 84. 3%),biomass( 68%)and abundance( 75%),with no significant seasonal variation. Shannon-Wiener diversity index( H') and Pielou evenness index( J) were used to evaluate the water quality in 13 sampling points,and the results showed that the water quality was good in Duobukuer Nature Reserve,the sampling points 5,6 and 12 presented β-pollution,and other sampling points were in an oligosaprobic-clean state.

On the basis of field investigation, specimen identification, and consulting a great deal of documents, this paper applied geographic flora to analyze the leguminous plants in the West Tianshan area systematically, and explored the impact of its diversity on ecotourism. There are 349 species of the Leguminosae, belonging to 44 genera, and the species number accounts for 15.42% of the total species number in the study area. The life form is dominated by mesophyte, and the ecotype is dominated by phanerophyte. Leguminous plants in the study area have relatively complicate floristic elements, stronger temperate nature, including 238 temperate species(68.19% of the total species number). There are 123 north temperate species and varieties, accounting for 35.24% of the total species number, the distribution pattern reflects climatic and geographical distribution of the West Tianshan area. Plants are able to conserve water resources, preserve soil and water, prevent wind and fix sands, adjust regional climate, purify air, maintain ecosystem balance, and build a favorable environment. On this basis, this paper analyzed the means of promoting the protection of plant diversity in the sustainable development of ecotourism.
