【摘要】 利用农业生态区域法计算出昕水河流域的耕地资源可承载人口为247 193人,表明已经超载;其次根据光合潜力的方法,推算出本区共可以承载486 385只羊单位,也明显超载;最后根据目前人类消费的用水定额,估算出每年总需水量约为4 375.6×104m3,与可利用的水资源量相比,也出现超载现象.这些说明昕水河流域的生态环境承载力不容乐观,需要尽快协调.更多还原

【Abstract】 Agriculture ecological region way was used to calculate plough land resource carrying capacity in Xinshui River watershed,Shanxi.The results showed that it carried 247 193 persons,and beyond this limit.Photosynthesis potential way was used to grassland resource carrying capacity and the results showed this valley could carried 486 385 sheep,and was over loading.Finally by the standard demand of man consuming water nowadays,the region needs 4 375.6×10~4 m~3 water per year.Compared with water resource available,it was also over loading.All the results showed that environment carrying capacity was not ignored in Xinshui River watershed,and need to harmonize as soon as possible.更多还原
