The study indicates that public-private partnerships （PPPs） can play ＂strategic＂, ＂practical＂, or ＂regulative＂ roles by making use of ＂instrumental＂, ＂institutional＂, and ＂normative＂ approaches in tackling political issues between countries. PPPs have often been discussed in studies of urban development, service provision, health care, and so on, but they have rarely been analyzed in terms of international relations and political problems on global environmental issues. This study takes an environmental problena---Sino-US energy and climate change cooperation--as a case study to inspect the possible roles and approaches of PPPs. Sino-US cooperation has been launched such as under the Strategic ＆ Economic Dialogue （S＆ED） by both administrations, which has significantly contributed to their reconciliation of domestic abatement policies in climate change, environmental protection, and energy. The establishment of schemes such as the Ten-Year Framework for Cooperation on Energy and Environment （TYF）, the EcoPartnerships, and wide-ranging dialogues and initiatives on clean energy and clean vehicles, in which both public and private actors participate, are among the important approaches of facilitating bilateral cooperation. The study concludes that these schemes have played strategic and practical roles in strengthening the degree of mutual trust and in facilitating the progress of cooperation, although more investigations are needed to considerate their regulative roles. The application of instrumental, institutional, and normative approaches have been observed through the implementation of the TYF and EcoPartnerships.

Vegetation types and climate conditions reflected by the modern phytolith assemblages in the subalpine Dalaoling Forest Reserve, central China

This research describes modern phytolith records and distributions from subalpine surface soils in the Dalaoling Forest Reserve, and reveals its implications for local climate conditions with respect to the altitude gradient. Well-preserved phytolith morpho-types, assem- blages, and climatic indices were used to study the relationship between local vegetation and climate condi- tions. The phytolith classification system is mainly based on the characteristics of detailed morpho-types described for anatomical terms, which are divided into seven groups： long cells, short cells, bulliform cells, hair cells, pterido- phyte type, broad-leaved type, and gymnosperm type. Phytoliths originating from the Poaceae are composed of Pooideae （rondel and trapeziform）, Panicoideae （bilobate, cross, and polylobate）, Chloridoideae （short/square sad- dle）, and Bambusoideae （oblong concave saddle）. Based on the altitudinal distribution of the phytolith assemblages and the indices of aridity （Iph）, climate （Ic）, and tree cover density （D/P）, five phytolith assemblage zones have revealed the five types of climatic conditions ranging from 1,169 m to 2,005 m in turn： warm-wet, warm-xeric to warm-mesic, warm- xeric to cool-mesic, cool-xeric, and cool-mesic to cool-xeric. The Bambusoideae, Panicoideae, and Chloridoideae are the dominant vegetation at the lower-middle of the mountains, while Pooideae is mainly distributed in the higher mountains. The close relationship between phytolith assembleages and changes of altitude gradient suggest that vegetation distribution patterns and plant ecology in the Dalaoling mountains are controlled by temperature and humidity conditions. Our results highlight the importance ofphytolith records as reliable ecoclimatic indicators for vegetation ecology in subtropical regions.
