The results showed that during 1953-2010, annual average temperature, annual average maximum and minimum temperature in Huanren County showed an increasing trend; annual precipitation showed a decreasing trend; there was a downward trend in annual dryness. The mutation of annu- al average temperature, annual average maximum and minimum temperature appeared in 1978, 1987 and 1982 respectively; there was no mutation of annual precipitation and dryness. On the whole, the climate of Huanren County tended to be warm and dry over the past 58 years.展开更多

The results showed that annual av- erage temperature in Huanren County showed a significant increasing trend in recent 60 years, and its linear tendency rate was 0.26 ℃/10 a. Tem- perature increase was in other seasons except for summer. There was a sudden change in annual average temperature in 1987, and winter average temperature changed suddenly in 1969 and 1985, while there were no sudden changes in average temperature in other seasons. Annual average evaporation also decreased, and its linear trend rate was -8.19 mm/10 a; average evaporation tended to decrease in spring and summer and in- creased in autumn and winter. In a word, the climate tended to be warm and dry in Huanren County.展开更多

It is also the needs of establlshing socialist harmonious society in China. It is an arduous systematic project in ethnic group regions of China to realize economic and sodal sustainable development,promote the harmony between man and nature andrealize the coordination among the economic development population, natural resources and envinonment To develop ecosystem construction and the green indutry well is the basic path to realize the above goals. Huanren Manchu Autonomous County in Liaoning Province is abundant in forests, especially local products, medicinal materials, tourism resource, water resources and culotte resources. In order to develop its ecosystem, the strategies should be focused on enhancing protection consciousaess, brand consciousness, science and technology consciousoess and market consciousness. The ultimate purpose is to create the top-ranking ecosystem environment, industry system, policy systern and district civilization.展开更多
文摘利用桓仁县1953 ～2010年逐月气温、降水和相对湿度资料,运用线性趋势分析、干燥度和伊万诺夫蒸发量等分析方法,对桓仁县58年来温度、降水和土壤蒸发量进行分析.结果表明,近58年桓仁县年平均气温呈明显的升高趋势,降水为下降趋势,暖干化趋势明显;月土壤蒸发量与降水量一样具有峰谷变化,土壤蒸发量5月最大,1月最小;58年来年土壤蒸发量呈增加趋势,线性倾向率为2.95mm/10a,土壤蒸发量除夏季为减少趋势外,其他各季为增加趋势;土壤蒸发量受降水量影响较大,若春季、夏季、秋季、冬季和年降水量增加10 mm,土壤蒸发量将分别减少3.58、1.20、1.51、2.48和2.48 mm.
