Huma County (simplified Chinese: 呼玛县; traditional Chinese: 呼瑪縣; pinyin: Hūmǎ xiàn; Manchu: Hūmar Siyan; Russian: Кумары) is a county in the far north of the Heilongjiang province, People's Republic of China. The county seat is located on the right (southwestern) bank of the Amur River, a few kilometers upstream from the fall of the Huma River (formerly also known as Houmar) into the Amur. It is under the administration of the Da Hinggan Ling Prefecture.
The opposite side of the Amur River is in Amurskaya Oblast', Russia, where there is a village with the same name in Russified form, Kumara (Russian: Кумара)[1]
History
Kumarsk, the predecessor of the present-day Huma, was a fortified Russian town in the Amur River region, founded in 1652 by Yerofey Khabarov and his companions, during his retreat from Achansk, corresponding to the present-day Khabarovsk, where he was besieged by Manchu and Daur allied forces.
On 13 March 1655, the Komar fortress, defended by the ataman Onufriy Stepanov and his 500 Cossacks, was besieged by a Qing army led by Ming'andali (明安達理) consisting of 10,000 men. The outnumbered defenders repulsed several assaults. The defeated Manchu lift the siege the following month (on 3 April 1655). The town was ceded to Qing Empire after the treaty of Nerchinsk in 1689.
Climate
Huma County has a monsoon-influenced humid continental climate (Köppen Dwb) with very warm, humid summers and severely cold, extremely dry winters. The monthly 24-hour average temperature ranges from −26.2 °C (−15.2 °F) in January to 20.6 °C (69.1 °F), and although temperatures consistently average above 10 °C (50 °F) from May to September, the annual mean, at −1.01 °C (30.2 °F), is low enough to form sporadic permafrost on sheltered sites, which is unusual for areas with this climatic classification. More than 70% of the annual precipitation occurs from June to September. With 2,595 hours of bright sunshine annually, sunshine is generous and no month averages less than half the potential amount.
