It is created on materials of maps of natural scale 1:5 000 000 - 1:80 000 000 and on literature data.Projection:
"Alber's Equal Area Conic" USSR, 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic contents:
Vector map. Area is shown by polygons (main distribution) and by dots (sporadic distribution). Zone of weediness is shown by polygons.Accuracy of the classifier:
Within the weed area, the area of main and sporadic distribution and the zone of weediness are shown where Ch. rubrum is a pernicious weed. The zone of weediness is established by criteria of occurrence of this species and abundance (Tanskii V.I. et al., 1998). In the limits of this zone, Ch. rubrum is characterized by 25% frequency of occurrence and 2 points of abundance.Method of map production:
Areas of main distribution, sporadic distribution and weediness are established according to the analysis of the open published maps and literature. The area of Ch. rubrum is based on the map taken from Hulten E. & Fries M. (1986). This area is extended in West and East Siberia according to Krasnoborov I.M. & Malyshev L.I. (1992), and in Central Asia according to Nikitin V.V. (1983), Ulyanova T.N. (1981), Keller B.A. et al. (1934). Limits of the zone of weediness are established according to Ulyanova T.N. (1981), Nikitin V.V. (1983), and Keller B.A. et al. (1934), being specified in accordance with data on abundance and frequency of the species occurrence taken from the following references and adjusted to the limits of arable lands. According to Ulyanova T.N. (1981), Ch. rubrum infests wheat in Crimea, West and East Siberia, Central Asia. Nikitin V.V. (1983) points out that Ch. rubrum slightly infests alfalfa and tilled crops in Central Asia. According to data of Keller B.A. et al. (1934), in Central Asia Ch. rubrum occurs in cotton crops. Sporadic distribution is shown according to Hulten E. & Fries M. (1986), Grossgeim A.A. (1945), Tolmachev A.I., (1976), Kharkevich S.S. (1988), Krasnoborov I.M. & Malyshev L.I. (1992).Reference citations:
