1·The main factor influencing variation in RWL was water regimes, relating to timing and intensity of water stress.
影响RWL变化的主要因素是水分，与水分胁迫的时间和强度有关。
2·Under different water regimes, spike number per plant (SNP), effective spikelet per spike (ESPS) and peduncle length (PLE) contribute a lot to the stable grain yield.
不同水分条件下，植株稳产性主要受单株穗数、有效小穗数及穗下节长的影响；
3·Water regimes exhibited no effects on bacterial-feeding nematodes, fungal-feeding nematodes, microbial biomass C and microbial biomass N during rice tillering and heading stages.
不同水分管理方式在水稻分蘖期、抽穗期对食细菌线虫数量、食真菌线虫数量、微生物量C和微生物量N没有影响。
4·Nanjing has a history of nearly 2500 years, and is known as the capital of six dynasties, or ten regimes, whose landscape incorporates mountains, water, city and forestry.
南京有近2500年的建城史，素有六朝古都、十朝都会的美誉，是融山、水、城、林于一体的生态型历史文化名城。
5·In this paper, the impacts of climate changes on karst ecosystem were studied from the aspects of vegetation and hydrologic regimes and water resource, taking karst areas in Chongqing as an example.
本文以重庆岩溶区为研究对象，从植被和水文水资源两个方面分析了气候变化对岩溶生态系统的影响。
6·The standards of field water control and potential of saving water, increasing rice yield and water productivity of these regimes are introduced and explained.
阐述了这些模式的田间水分控制标准以及节水、增产和提高水分生产率的潜力；
7·The ecosystem of the source area of the Yellow River, taking the hydrologic and the water resources regimes as the basic indexes, has been changed remarkably during the recent years.
以水文水资源情势为核心的黄河源区环境生态系统近年发生了显著变化。
